    And then there is the constant force of the air resistance. Humans going headfirst are moderate aerodynamic. Terminal velocity is about 200 mph. But the speed of sound is 2 1/2 times that. So you would be looking at a sustained force of at least 2.5Gs while going Mach 1. This is survivable, but not comfortable for long durations.
