The U-2 Dragon Lady is probably one the most difficult plane to land in the world.
That’s why, U-2 spyplanes need chase automobiles to supervise take offs, landings (and touch and gos).
Such sport cars are driven by highly trained pilot who act as ground-based wingmen for pilots flying aircraft whose size is such that the pilot’s view is obstructed by the airframe or part of it, and there’s a significant risk of hitting any ground obstacle with a wingtip.
Both manned and unmanned planes rely on chase cars, 20 of those are located across the globe.
Anyway, watch the video, showing several crash landings or overruns!
H/T to Tony Lovelock for the heads-up
