There are two Army attack helicopters seen near bases in the United States. This one has wheels (reversed fixed tricycle gear); the Bell AH-1 HueyCobra doesn't. And this is the one that can fly upside down, a stunt sometimes performed at air shows. Otherwise, huge armored engine nacelles over stubby outrigger wings; angular greenhouse cockpit; bumps and lumps for avionics and weapon systems; and rarest of all helicopter gear, a tail wheel.

In service since the mid-1980s, and a very successful machine in Operation Desert Storm, the Apache looks like hell on wheels when stripped; when armed with rocket launchers, like hell itself. Like the MBBs, it can fly in negative g — that is, it can push itself down.
