Intro
The C-17A is a four engine aircraft with a high wing configuration and a military airlifter that was first built by McDonnell Douglas and later by Boeing after they merged. The aircraft is also known as the Globemaster III and is capable of transporting heavy loads of both military cargo, vehicles and troops as well as performing operations from small airstrips and to drop cargo off from the air.
The four Pratt & Whitney F117-PW-100 turbofan engines each provide a very powerful thrust of 40,400 lbf (179.9 kN). Each engine has a built-in feature for the reverse thrusters, which enables the engine to produce a very powerful reverse thrust. This reverse thrust can help the C-17A to a full stop within just 9 seconds. The reverse thrust can also make the C-17A taxi backwards with up to 20 mph (30 km/h) if needed to.
