with earth rotating at 1000mph, when we launch ourselves from a trampoline how are we landing back at the same spot compared to launching from a moving car

Question

If we jump high enough to reach a hang time of 1 second, the earth would have moved quarter mile.

Also, why haven’t we devised something that allows us to stay suspended instead of using airplanes with max speed of 500mph

Answer 1

Best guess is that the air around you is moving at the same relative speed as the you when you jump off the trampoline, unlike a car where you are being pelted by wind friction.
