Yep you guys answered that one pretty quickly. Thanks for the answer! I was thinking it dropped off a little faster than that but that physics class was 3 years ago lol  :old:

Just keep this in mind, gravity pushes not pull.

This is only half correct concerning the particles of pair-production, particular matter particles will accelerate in the direction of the gravity field while the corresponding antimatter particles will accelerate away from it.

Col. Joseph Kittinger did it, 76,400 feet. Also the first man (and only as far as I know) to break the sound barrier with his body.

1st jump was from 76k but the big jump was from 102k.

Your right, I think I forgot some of the specifics.

^ he Did not break the sound barrier.

Regardless if gravity is modeled at all, at 70k in AH the only aircraft capable for us is the me163, which although fun for S's and G's has nothing do do with the game at all.  Put a wishlist up asking for airspace to be modeled correctly at that altitude and see where that gets you  :lol
From all of the articles I have read, he did momentarily break the sound barrier.

It won't make much of a difference BUT, since you asked, the formula for force due to gravity is the inverse square of the distance.



F= Force due to gravity
G=Gravitational constant
m1= Mass of body 1
m2= Mass of body 2
r= radius from center of mass of body 1 to center of mass for body 2

As the radius (r) increases the force is affected by the square. So, simply put, you double the distance you get a forth of the gravity. A plane flying at 30,000 feet only increases that radius by about .1% over sea level. Such a tiny difference when compared to the gigantic numbers involved.

Not sure if it's still the same or not but at 98K in a 163 the plane would just disappear on you.  You'de still be there but no more plane.

I can't tell you about high alts but gravity is very effective down low...... I know this from experience.


I would post film but they always burn in the ensuing fire.
