I guess that is one way to exceed the sonic barrier. Too bad it doesn’t work with light.
The SW Airlines flight was just 67mph short of the speed of sound. They would have to ride a lightning bolt to reach the speed of light. However, the sudden stop downward wouldn’t be worth it. Maybe the could catch a ground to cloud lightning bolt ride.
Doesn’t work with sound, either.
Buy a tail wind is also a head wind. Going the other way might be a problem
