I am researching the 2nd ARU - what was your job on the ship and what stories can you tell me about the mission? Ken

Every household will someday have a helipad and chopper. Sure as God made little green apples. Is the helicopter described in the book of revelation in the Bible ? What happened to the autogyro ?
The helicopter is surely a wonderful addition to the engineering designs of any society. Respond if you have time

Sorry for the late reply.

I like it too. I especially like how it had cables rather than a drive shaft connecting to the tail rotor. I have noticed that Kobe Bryant made a comment on here as well. How strange is that?

its cool

We had 2 Sikorsky R-4's flying from a small flight deck on our ship -- 2nd Aircraft Repair Unit (Floating), which supported B-29 bombers flying from Saipan and Iwo Jima. All of the high tech shops to support the B-29's were installed on the Liberty ship -- parts and men were ferried to the air strips at Saipan and later at Iwo Jima.

A surprisingly mature looking design for a first off like this aircraft. All modern single rotor helicopters look like this

I have some pictures of the HNS-1 at Goose Bay that my father took.

Long shot, does anyone know where I can obtain a DVD of a 1980s doco called "The Chopper"? I have no idea who produced it, exact year, or who the English-sounding narrator is. It includes interviews with Hanna Reitsch and Bart Kelly (coworker of Arthur Young at Bell), and other techs and pilots, as well as footage of the prototype NOTAR, Apache, Sikorsky ABC and the XV-15, as well as the R-4.

In 1947,I was instructor at the R-4 Helicopter Maintenance School at Shepard AFB in Texas. I went on some test flights of the R-4. For the times, it was quite amazing.

How was the helicopter used to attack a submarine with no war material.
