How to improve the Spit?
Invert the fuel injected engine and build in a 20mm motor cannon to fire through the nose like it was designed to do in French fighters. This would improve view over a more sloped nose, give better dive, easier to recock a jammed cannon in the air and it doesn't freeze. Long range accuracy of a powerful central cannon fully harnesses the strengths of the Hispano.
If the RR engine can't accommodate it, make a twin-engined Spitfire (Whirlwind style). Put 3 or 4 Hispanos in the center nacelle with the ammo at the cg. Torque could be neutralized, improving stall performance.
Long-range could easily be improved with more room for petrol. Add Fowler flaps to restore aerobatics of the smaller forebearer. Enlarge wing, elevator and tail surfaces as well for that purpose. Top it with a bubble canopy.

No more weak initial dive.
No more range limits beyond point interception.
No more dicey stall-turn. No torque.
No more narrow wheel struts.
No more restricted view all-around.
No more weak MGs, but a nose all-cannon battery.
No more jammed cannon.

Give credit to Anthony Cooper and his 'Darwin Spitfires' site.
The test was done by the RAAF in August 1943.

His stall chart didn't translate too well here though.
A hard turn in the MkVcT (6G) had a stall of 212 mph clean (or 184 knots IAS);
@ 20,000' stall was 296 mph TAS;
@ 30,000' it was 338 mph.
349 mph was the maximum level speed @ 30,000' so no wonder the incidence of accelerated stall was high at Darwin!

Not being familiar with knots, I used 1.15078 for mph calculation.

Mk Vc vs Zero 32:

Thus it is doubly ironic that the Spitfire’s reputation would habitually be established by reference to archaic, non-tactical criteria, and that the new Japanese opponent would trump every one of the Spitfire’s purported trademark virtues: in effect, ‘whatever you can do, I can do better’.

However, despite the gloomy overall assessment provided by the comparative tests, the relative situation was not unfavourable to the Spitfire. Given that the strong fighter and AA defence over Darwin forced the Japanese to penetrate Australian airspace above 25 000 feet, the Zeros were thereby forced to play to the Spitfire’s strengths. Moreover, given the tactical situation of intercepting bomber formations, the Spitfires would generally be coming down in a high speed dive, which was also advantageous. 1 Fighter Wing’s recommended tactics at this point were correct: either to zoom back up after firing or disengage by continuing the high speed dive downwards. Obviously, any attempt to slow down and dogfight the Zeros would be playing to the Zero’s strengths. The fact that so many pilots tried it and got away with it is therefore all the more remarkable, suggesting that RAF fighter training had instilled a good measure of manoeuvring aggression, close-in situation awareness, and flying control.

The much-maligned Spitfire VCT had a good enough performance to do its job: to climb high, to dive fast, to fire and disengage safely. Indeed, in these respects it had similar tactical characteristics to other early-war allied fighter aircraft - such as the P-39, P-40, and F4F Wildcat – in that it possessed a clear superiority in one tactical mode: diving fast into the attack and then performing rolling downward evasion. On top of that, it shared with the F4F the ability to climb above 30 000 feet – the tactical vantage point from which attacks were delivered. These were its most relevant tactical characteristics. In that sense, the Spitfire was no more and no less than a typical allied fighter of the earlier part of World War II – good enough to do its job, but not good enough to establish superiority over the enemy.

I had to continue the RAAF Spit vs Zero test at Darwin due to it's length:

...In a modest 3G turn, the Spitfire would stall at 130 knots IAS, which equates to a TAS of 242 knots at 20 000 feet. At 6G (a hard turn or pull out at high speed, with the pilot blacking out), the Spitfire stalled at 184 knots IAS, which equated to 257 knots TAS at 20 000 feet, and 294 knots at 30 000. The latter was only 11 knots less than the Spitfire’s maximum speed at that height (at the emergency power settings of 3000 rpm and plus 2 ½ pounds boost), so it is clear that as height increased, the pilot found himself stuck in an increasingly narrow corner of the flight envelope, until any attempt to pull G would result in an instant high speed stall. This helps to explain the high incidence of Spitfires stalling and spinning out of combat turns over Darwin in 1943.

Spitfire VC Stalling Speeds[4]


Stall IAS, knots

Stall TAS 20 000 feet

Stall TAS 30 000


































By contrast, the Zero’s lighter weight meant that it would always be superior in all tight manoeuvres. Obviously, the Zero also stalled out under G, but the tests showed it to have superb handling characteristics in hard turns, with no tendency to spin out of high speed stalls (implying that it was superior to the Spitfire in this respect). Although Spitfires endeared themselves to pilots by their sweet flying qualities, it is clear that the Zero too had impeccable manners.

If a Spitfire followed a Zero around in a loop, it would stall out at the top, and could only stay behind the Zero for Ύ of a horizontal turn. In short, it was too easy for a Zero to evade a Spitfire at medium altitudes and below, by simply performing any vertical manoeuvre or hard turn. This meant it would be very difficult for a Spitfire to get a shot at a manoeuvring Zero. The only practical firing opportunity for Spitfire pilots would come in a bounce.

Neither aircraft had a good roll rate at high speed, due to their ailerons locking almost solid in the airflow. However, in this respect the Zero was even worse than the Spitfire, which permitted a glimmer of encouragement for the Spitfire pilot: the Zero could not get into a firing position behind the Spitfire if the latter evaded in diving aileron turns at high speed. Other than the downward break, no other evasive manoeuvre by the Spitfire was likely to work, although a vertically-banked climbing turn was difficult for the Zero to follow. Otherwise, the Zero could follow the Spitfire through any manoeuvre below 220 knots, and could use its slow turning advantage to get onto the Spitfire’s tail after 2 ½ hard turns.

It was only at higher speeds that the Spitfire started to enjoy a relative advantage. Because the Zero’s controls stiffened up even more rapidly than the Spitfire’s, the Zero had great difficulty in following the Spitfire through high speed manoeuvres where the pilot pulled a lot of G. From about 290 knots, the Zero had great difficulty following the Spitfire through diving aileron rolls. The conclusion was that the Spitfire was more manoeuvrable above 220 knots, while the Zero was the better below that speed. Reflecting this set of opposite characteristics was the fact that the Zero’s standard evasive manoeuvre was the very opposite to that of the Spitfire – upwards rather than downwards, in the form either of a climbing turn or a vertical aerobatic manoeuvre like a loop, stall turn or Immelmann.

Overall, the summary from the comparative trials was not encouraging:

'Both pilots consider the Spitfire is outclassed by the Hap at all heights up to 20 000 feet…The Spitfire does not possess any outstanding qualifications which permit it to gain an advantage over the Hap in equal circumstances.'[5]

The conclusions of Wawn and Jackson only corroborated the earlier evaluation conducted by 1 Fighter Wing HQ[6] after combat experience over Darwin, which found that the Spitfire had a higher maximum speed, that it was more manoeuvrable at high speed, and that it could be dived to a greater speed. It followed that the only sensible offensive tactics were the dive from height followed by a zoom climb for a re-attack. The recommended evasive tactic when under attack was to break downwards into a vertical dive at full power, while yawing the aircraft violently by uncoordinated use of the rudder and/or ailerons to put the Zero pilot off his aim. Once the speed had built up (presumably 300 knots), the pilot should start rolling into downward aileron turns to obtain a clean separation from the Zero.

Rightfully, a whole generation of pilots learned to treasure the Spitfire for its delightful response to aerobatic manoeuvres and its handiness as a dogfighter. However, it is odd that they had continued to ...

I'll insert this RAAF Spitfire vs Hamp comparison test:

The Model 32 Zero, with its squared-off wingtips, was regularly encountered both over Darwin and New Guinea in 1943. Known to the allies by the reporting name ‘Hap’ to distinguish it from the round-wingtipped ‘Zeke’, the Model 32 was an improved model over the original Model 21 with which the Imperial Japanese Navy had fought its 1941-42 air offensives. The chief difference lay in its more powerful Mitsubishi Sakae 21 engine, which developed 1130 hp (as compared with 940 hp in the Model 21). The more powerful engine was heavier, requiring a reduction in fuel capacity from 518 litres to 470, and more thirsty; thus range was less than that of the earlier model. Both the newer and older types were encountered over Darwin.

Nonetheless, it was a Model 32 Zero that was captured and rebuilt, permitting the trials to occur in August 1943. The 1130hp of the Model 32’s Sakae 21 engine was quite comparable to the 1210 hp of the Spitfire’s Merlin 46, but the Model 32’s weight was much less – 5155 lb compared to the Spitfire’s 6883 lbs. As a result of this structural lightness, the Zero had both a superior power loading (4.5 lb/hp versus 5.6 lb/hp) and a lower wing loading (22 lb/ft2 versus 28 lb/ft2).

These differing technical characteristics determined the pattern of relative performance between the two machines, as shown by the tactical trials conducted by two experienced RAAF fighter pilots in flying trials conducted over three flying days[2]. Flight Lieutenant ‘Bardie’ Wawn DFC and Squadron Leader Les Jackson DFC flew against one another in both aircraft, and what they found was not encouraging.

They found that the Zero had a lower rated altitude than the Spitfire, 16 000 feet against 21 000 feet, which delivered the Spitfire a good speed advantage at height – it was 20 knots faster at 26 000 feet. However, as had already been noted by RAF Fighter Command in Europe, the Spitfire had relatively slow acceleration, and thus the Zero was able to stay behind the Spitfire within gun range while the Spitfire gradually accelerated away out of range. Even in a dive the Spitfire still accelerated too slowly to avoid the Zero’s gunfire. Climbing away was also not an option, as the Spitfire’s climb superiority was too slight (not to mention the slow acceleration problem once again).

The only offensive solution for the Spitfire was to attack from a height advantage, to maintain a high IAS on the firing pass, to fight on the dive and zoom, and to pull high speed G. Slowing down, or being caught while flying slowly, would clearly be very dangerous, for the Spitfire would be unable to evade. Above 20 000 feet, so long as the Spitfire started with a 3-4000 feet height advantage, the Spitfire could make dive and zoom attacks with impunity.

The height advantage of the Spitfire VC was also shown by the British machine’s superior operational ceiling. Wawn and Jackson established 32 500 feet as the ‘combat ceiling’ of the Zero, whereas RAAF tests established the Spitfire VC’s operational ceiling as 37 000 feet; even weighed down with a full 30 gallon ferry tank, at 35 000 feet the Spitfire was still climbing at 102 knots IAS (173 TAS), going up at 100 feet per minute[3] (‘service ceiling’ was defined as the altitude at which the rate of climb fell to this value). The superiority of the Spitfire’s ceiling is corroborated by its 5000 feet higher rated altitude, by 1 Fighter Wing’s demonstrated tactical employment of the Spitfire at heights up to 33 500 feet, and by the Zero pilots’ avoidance of the height band above 30 000. The pattern established in these tests confirmed the findings of operational experience over Darwin, where the Spitfires were always able to dominate the upper height band without Japanese challenge.

The Zero developed its maximum speed of 291 knots at its rated altitude of 16 000 feet. The Spitfire produced 290 knots at 15 000 feet, confirming that below 20 000 feet the two types were more evenly matched in speed performance. Given the Zero’s much superior acceleration, in practice this meant that the advantage tipped more heavily in favour of the Zero at these lower altitudes. In comparative tests at 17 000 feet, the Spitfire was again unable to safely draw away from the Zero. The unanimous conclusion of Wawn and Jackson was that ‘the Spitfire is outclassed by the Hap at all heights up to 20,000 feet’.

As was already well known, the Zero had all the advantages in combat manoeuvrability at slower speeds. This was a product of the Japanese machine’s superior power loading and lower wing loading. The Zero stalled at only 55 knots, whereas in clean configuration the Spitfire stalled at 73. Being able to fly more slowly while still under complete control meant the Zero could fly tighter turns without stalling out. The stall speeds cited apply to straight and level flight at 1G – hardly a realistic scenario in combat, where pilots would typica ...

The tropicalized Spit Mk V did battle the A6M3 Zero as well as a few Oscars over Darwin for 5 months with somewhat unsatisfying results for both sides. The Spitfire could beat the Zero up high but that's where the cold sensitive Hispano cannons often failed to perform. Its short range was another very costly limitation. So it wasn't simply a just a matter of Spitfires spinning out of control trying to duel with Zeros. They already learned not to turn with Oscars and Zeros.

The Spitfires at least held their space and the Japanese air raids departed Darwin finally. But Spitfire losses were high. How high were Japanese losses?
The controversy over which side lost what won't be settled here. But the fact is neither side felt very victorious dispite the conflicting claims.

It's amazing that so few people know that the Zero and Spitfire really met in combat.
Over Darwin many aces on both sides were among the pilots so
that was about par. The A6M3 didn't have the reliability problems with their cannons like the Spitfires did. I believe they weren't the low velocity 20mm cannons of the older A6M2 either. It could still turn 180 degrees in 6 seconds flat and out range the Spitfire V by many orders of magnitude surprising the interceptors by their mere presence. If it was the Model 33 Hamp, it had improved roll and speed with clipped wings. This was before the new more powerful Zero engine got weighed down as with following models so its acceleration was still great.
It's no wonder the aging Spit V had its hands full over Darwin.

Supermarine Spitfire
Το Supermarine Spitfire υπήρξε ένα από τα πιο διάσημα καταδιωκτικά αεροσκάφη όλων των εποχών, σύμβολο της Βρετανικής αεροπορικής ισχύος και χρησιμοποιήθηκε ευρύτατα από τη RAF και τις συμμαχικές αεροπορίες κατά το Β΄ Παγκόσμιο Πόλεμο και τη δεκαετία του ΄50.

Κατασκευασμένο από τη Βρετανική Supermarine το Spitfire ήταν μια δημιουργία του αρχισχεδιαστή της εταιρείας R. J. Mitchell, που συνέχισε να τελειοποιεί το σχέδιό του μέχρι και το 1937 που πέθανε από καρκίνο. Οι ελλειπτικές του πτέρυγες του επέτρεπαν ανώτερες ταχύτητες από το Hawker Hurricane και άλλους ανταγωνιστές του, του έδιναν δε μία χαρακτηριστική εμφάνιση, ενισχύοντας την όλη του αεροδυναμική εικόνα. Ιδιαίτερα αγαπητό από τους χειριστές του, το Spitfire χρησιμοποιήθηκε καθΆ όλη τη διάρκεια του Β΄ Παγκοσμίου Πολέμου και τα αμέσως μετέπειτα χρόνια, σε όλα τα θέατρα του πολέμου και σε πολλές παραλλαγές.

Περισσότερα από 20.300 τεμάχια όλων των τύπων κατασκευάστηκαν, συμπεριλαμβανομένου και ενός διθέσιου εκπαιδευτικού, ενώ κάποια από αυτά συνέχισαν να χρησιμοποιούνται ακόμα και στη δεκαετία του Ά50, όταν τα αεριωθούμενα είχαν πια επικρατήσει. Αν και ο μεγάλος του αντίπαλος, το Messerschmitt Bf 109, το συναγωνίστηκε σε στατιστικά παραγωγής, το Spitfire υπήρξε το μόνο Βρετανικό καταδιωκτικό που παρέμεινε σε συνεχή παραγωγή πριν, κατά τη διάρκεια και μετά το Β΄ Παγκόσμιο Πόλεμο.

"4. The speed of sound does not vary with aircraft attitude."

I think you're almost correct. The speed of sound varies with the density and pressure/temperature of the gas(es) involved. Ask Gen. Yeager why he flew the X-1 in a climb instead of a dive to break 'the sound barrier', if you get a chance.

Regardless, the Spitfire is one beautiful aircraft.

A number of points...
1. The speed of sound in air is a function of barometric pressure, temperature and humidity.

2. The figure 761.2 mph is valid only in an ICAO Standard Atmosphere at Sea Level.

3. While the above data would have been available from the recording instruments carried by Flt. Lt. Ted Powles' Spitfire PR-XIX, PS852, the instruments were never designed for recording this data in a very rapidly changing environment such as would have been encountered in a high speed dive. Consequently, the readings are questionable. Without knowing the degree of accuracy available from each instrument, it is impossible to accurately reconstruct the flight's proximity to Mach 1. To be accurately informed as to the accuracy of the instruments, one would need to consult either official documentation or an instrument technician familiar with the types of instruments carried by PS852 on February 5, 1952 out of Kai Tak, Hong Kong.

4. The speed of sound does not vary with aircraft attitude.

5. Different parts of the airframe will have different Mach numbers, owing to local fluctuations in airflow.

6. It was the thin wing cross-section of the Spitfire that gave it a higher critical Mach number than any of its contemporaries, including the early jets.

I was in the Air Force in 1947 after the war,Group 1 instrument maker, @ No 1 PRFU Finningley.I can remember being upside down in a Spit cockpit working behind the blind flying panel, a tight squeeze. The gun sight filled the front screen space.

Using Mach speed for dives is tricky.
If the Mach 0.891 dive was 606 mph, then that computes to 680 mph for Mach 1. That was in the 1940s
If the Mach 0.94 dive was 680 mph, then it is 715 mph for Mach 1! That was in the 1950s.
Another site online uses 692 mph to convert to Mach dive speed. So forget the post of 761.2 mph I was using before.
It is obviously for level speed.
What does your math say? I could be wrong again.
What should still show is the relative dive performance of the planes, by either measure (mph or Mach). Alas, there are varied results that can be found in contradiction to that line of thinking too.
Then I tend to make excuses like weather, pilot's courage to push the envelope, design stability, and structural strength.
So, if you read some of my posts in the past that seamed off, bear these points in mind.

I worked on the later versions of this beautiful A/C in 1966 on the Historical Aircraft Flight at RAF Coltishall we had 3 Spitfires and 2 Hurricanes all in great flying condition, they did airshows and practised regularly at Colt doing beat ups down the Lightening pan, I wonder where they are now. I would love to see one at the Reno Air Races to give the P51 Mustangs some competition. The sound of a Merlin on full chat is a sound to behold.

I am 58 and my father (now deceased) flew spitfires in the 54 squadron. I still have all his flight books and always loved hearing his stories of defending Darwin Australia during later part of the war. He loved Australia so much we moved out here from UK when I was 5 after he returned from the war.

I was a flight mechanic engines , my squadron had the mark 24s, ground attack fighter, they never gave much trouble, needed a plug change occasionally or a prop change, the pilots loved them, dumped for D H Hornets in 50 or 51.

Col. Larry Guarino USAF ret, e-mail, 18.01.2011 22:50

I flew the Mk5B and C. Only difference that I recall was the B had a metal prop.Then I flew mostly the MkVIII and the MkVIIIC. The eight had pointed wingtips and blower cut in at 21,000 ft. The C had rounded tips and blower cutin at 14,000 ft.The US Army Air Corps had two groups, 6 squadrons flying the Spit from the landings in Africa to Anzio. Also flew most models of the P-51 to the K model. Cant compare the aircraft, both wonderful. Spit was basically an interceptor with limited range. The Mustang could fly from England to Berlin and back.

I am 81 years old. During WW2 I lived three miles from Hornchurch Aerodrome. My Dad took me there in 1938 for Empire Air Day. I remember the day it was bombed. My Dad worked in Hornchurch (WW1 veteran). We would go to the airfield gates and watch our heroes head out for R7R in London. Great chaps. We will never forget them.

Which planes are drawn on the previous page ? I see a: A10 (groundhog), a: flying boat (dornier perhaps ?), and there's a twin engined, inverted gull wing plane wich i'd like to know. Thanks in advance for reply. ps Nice site.

I'm Australian, 70 years old and have loved Spitfires since I was a kid. I have the MS FS2009 Flight Simulator on my Computer and my Spitfre collection is my favorite.

I saw the reference to Squadron Leader J. R. Tobin. My name is Robert C. Tobin. I am probably not related to J.R. Tobin. I would love some information about this gentleman.

Guys, the speed of sound in air depends on temperature more than anything else. It's about 331.3m/s at 0 degrees C and 343m/s at 20 degrees C. The formula for local speed of sound is S = 331.5 + 0.6 x T (degrees C). Thus, the local speed of sound usually increases as the aircraft dives (and the local temperature increases) so that the aircraft becomes, once more, subsonic and therefore controllable. We don't have any data for the temperature at altitude during these incidents, but it could be assumed fall at around 2 degrees C per 1000' of altitude. The surface temperature in Hong Kong varies considerably, however, both seasonally and diurnally.........

Some years ago my friend Des McKenna( LLOYDS medal Chief Engineer MN WWll )and I were running a passenger tug up the Rideau River in Ottawa Ontario. It was Battle of Britain Day and just as we passed under the bridge for HuntClub we heard the noises we had both grown up with.

A Spitfire and a Lancaster Bomber coming from the eastern bank of the river where the air port sits above the river valley.

Unbelievable ------He remembered their noise from the days he ran ships in convoys in the Atlantic.
Me being younger, remembered them taking off on missions.
Most of the passengers had never heard them, nor heard of them.
Great Day.

Ron, e-mail, 20.09.2010 06:27

The Mach .94 episode over Hong Kong by Ted Powles was in the early 1950s (1953 I think). I was passing on what I read, but if your sure I'm wrong, then I appreciate the correct info. I was thinking the wing was the new one like that in the picture (not saying the Mk in the photo).
I am aware that the earlier incident of Mach .891 has been reported as a Mk XIV or a Mk XI by different ones.
Sometimes the source has an obvious typo with an improper Roman numeral in the Mark. Keeps things mysterious I guess.

sorry finger trouble in my last comment it should be MKXIV not MKXVI

Ron, you have your marks of Spifire mixed up , the picture above is of PK312 a MK22 with the re-designed wing,this aircraft was then retro-fitted with the Spiteful type tail as fitted to MK24's. The PRXIX you mention was essentially a MKXIV with arnament removed, F24 cameras,pressure cabin and a wet wing as fitted to the PRXI, it did not have the same wing as the late production MK21's, MK 22's & MK24's had.

For some beautiful flight scenes, get the dvd "Piece of Cake"..Story of an RAF squadron prior to and just after WWII started...Basically the movie ends at the beginning of the Battle of Britain...Another good movie is "Spitfire" aka "First of the Few", the bio of R.J. Mitchell...

Ron, e-mail, 02.09.2010 08:05

Ian, you have a good point.
My posted ratio may work for level speed @ SL.
The Spitfire Mk 19 (with the new wing as pictured at the top) was surveying atmospheric conditions over Hong Kong when it lost control and dove from 51,550' recording 690 mph or Mach 0.94 terminal velocity. RAF pilot Ted Powles regained control and pulled out under 3,000' altitude, landing safely. But his data was regarded as highly questionable.
I don't know what altitude the max dive speed was recorded at. What was it for the (eliptacle wing) Mk XI when it reached 606 mph or Mach 0.891? The ratio is different. But then that one isn't in doubt so much either.

Ron, e-mail, 28.08.2010 18:28

The calculation for the speed of sound changes with altitude.
The S.L. ratio is obviously level flight.
The question was: What is the ratio and altitude of your results, Ian?

Ian Cognito, 29.07.2010 13:42

If you try to break the speed of sound at SL in a dive, you don't get to tell anyone about it. Even over Death Valley.

Ron, e-mail, 29.07.2010 08:43

Please explain your dive speed for Mach .891, I thought the ratio was 761.2 mph at SL for Mach 1.

grady stoodt, e-mail, 08.05.2010 16:58

i agree with gordon williamson. Ithink that the spitfire is the most beautiful plane ever to fly. I think of the spitfire as sort of a fighter version of the avro lancaster. or the other way around.

As far as looks go, the Spit is right up there with the Mustang. Saw a few while serving at Greenham Common in 1956, Jolly Good Show Mate. My hat is off to all the young men who flew this plane into combat and won the Air Battle over England.

paul scott, e-mail, 15.10.2009 21:57

As Ember says, the armament was pretty bad but a superb machine nevertheless. Everyone's got their favourite, it's easy to say the Mustang, even the P-47, or the F-4 Corsair, the FW190, but probably the Mustang had it all, with its long range.

Ian Cognito, 23.09.2009 09:32

The true adventures of Sqd Ldr's Tobin and Martindale diving a specially instrumented Spitfire XI are well documented. The Mk XI had a clean wing without gun blisters and ports. The aircraft, EN409, had a special Rotol propeller which could be fully feathered. They achieved 606 mph, Mach .891 although Martindale had to glide in since his prop flew off.

Ronald, e-mail, 23.09.2009 07:08

When the Spitfire fought Sagittarios over Sicily it met it's match. If one got on it's tail, it could not be shaken. Even in diving turns.
Enter the Mk XIV. Dive red-line was 647 mph, terminal velocity was said to be 677 mph! (mach .89)

US used Spitfires?

And what are the versions of the three,four and five bladed Spitfires?

Ronald, e-mail, 23.06.2009 04:57

The Mk 1 Spitfire took 19 seconds to turn full circle.
Best roll-rate was 105 degrees/second @ 200 mph.
The clipped wing Mk V rolled 150 degrees/second @ 200 mph.

Richard James, e-mail, 22.11.2008 17:16

There is as saying in engineering, 'If it looks right it is right', it was more than 'right' it was perfect! To watch a Spitfire in flight and to hear the Merlin is pure magic.

Ronald, e-mail, 20.09.2008 09:27

The US was wise to have some Spitfires in their inventory.
It was good at turns even at high altitudes which it could reach quickly. This was helped by it's small internal fuel load which is fine for a short range interceptor.
After it finally developed the engine to follow a German in a negative 'g' dive and grew a pair of cannon, it could survive quite well, thank you. Even in the Pacific it was good for interceptor work. It wasn't sturdy enough to really excel at carrier landings though. The Mk VIII followed the Mk IX (curiously enough). It was strengthened and longer ranging. The Mk VIII was a pilots favorite to fly. By the time the Mk XIV went into action in western Europe the Luftwaffe largely abandoned the higher altitudes to it. This Griffin powered Spit was a sensational performer but was a handful for the pilot too. Later Mk XIVs finally had teardrop canopies for better view.
The first Allied type to bag the Me 262 jet says more than I can.
