64 miles sounds quite far, and I've gone quite fast on my motorcycle, but the top speed of the F-35B (that they tell us) is 1,200 mph. At that speed that's just over 3 minutes.
> The jet had flown for 11 minutes and 21 seconds after Del Pizzo’s ejection, slowly climbing as high as 9,300 feet.
After about 11 minutes, the report said, the jet banked down and started descending to its right, clipping the treetops of a forest along the way before crashing. The report said no one was injured by the crash, but it did damage several trees and crops. The $100 million jet was shredded into pieces and a total loss.
If a car drove at highway speed for 3 minutes without crashing after the driver jumped out, you'd be impressed too.
