Flying machines

Aircraft are flying machines. They counter the force of gravity by using either static lift or the dynamic lift of an air-foil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include air-planes, helicopters, airships, gliders, para-motors, and hot air balloons. Uncommon examples include ornithopters.

In USA, the NTSB is charged with investigating accidental air crashes, so they must pass responsibility to the FBI if they believe foul play may have been involved. The FBI is free to disagree and re-declare it a non-criminal matter (as they did, for example, with TWA Flight 800).

This system gives the US Deep state a double chance to declare assassination by plane crash to have been a simple accident.
