Yeah, so downwind and didn't make it. Throw it from a plane, dive vertically to the ground and lithobrake, you are sure to "break" "world speed record" even more.
Apparently, Felix Baumgartner ("passive" skydiver) reached 380 m/s (1368 km/h) in "free fall", so you have a long way to go...
You can call an event "landing" if the flying device is able to fly again without repairs ("airworthy").
If this is to be a competition and a "record" in anything, there should be rules like: - it starts and it lands airworthy, - airspeed measured, not ground speed; for test runs on windy day you can average downwind and upwind; etc.
Benjamin Biggs of Drone Pro Hub has once again broken the drone speed record with the latest iteration of the Black Bird. This new version of the drone managed to hit an astonishing top speed of 730 km/h (453.6 mph).
