    I have jumped out of more than 30 planes in my lifetime. Not a single time was the wind below 4 mph. It almost feels like they want it to fail.

    I am not sure I understand why they are worried about ground winds anyway, I have jumped many times in excess of 10 mph.

    EDIT: Sorry my post was peant as a response to this one:

    [​IMG]

    Look at the graph again. The attempt is (was?) to jump from 23 miles or 36 km. That's where density is close to 0 and speed of sound is the lowest at 300 m/s (except in thermosphere). Down to 10 km speed of sound is even lower (~290 m/s) and density is still less than 1/3 compared to sea level.

    He has about 26 km to reach 300 m/s and he will make it.

    They have some very smart people working on this project. Those very smart individuals say 690 mp/h. No amount of graph reading I learned in the 6th grade will make me think I know more than them.

    A caveat to that is maybe he is trying to break the sound barrier in an environment that is close to that of the surface.

    300 m/s is close enough to 690 mph that it's basically the same.

    the ground wind could wreak havok on takeoff... and it will change where it will land.... i dont think he can change course once he takes off.

    Also wind could interfer with whichever experiments they want to run. Wind changes pressure for example.

    What a PUSSY! Just take the thing up and jump! Really afraid of 5mp winds? YOU WILL BE GOING FASTER THAN THE SPEED OF SOUND DIPSTICK! WTF????

    There is very little air up there. And sound needs a medium to travel in. And less air means less friction.

    that small amt can shift him off his bearing and course, heck he dont make it he either slams into the ground or some other structure or mountain.

    He might aswell jump out of a Dragonlady or A12
