Yes, I am interested by the simulator code.
Also, one thing does not seem obvious to me: I understand why the
velocity will be *high* but why are you expecting stability problems?
First of all, gravity will be the only driving force pulling down (no
energy will come from the skydiver, he/she will be "passive"). Second,
the atmosphere density will be *small* up there. The terminal velocity
will be reached when the force due to the gravity pull * mass of
skydiver will equal the force of drag the skydiver is creating due to
his/her passage thru the atmosphere.
Intuitively to me, there should not be any difference with the feel of
"regular" terminal velocity.
Also, why the 1.3 g? Should it not be 1? How could it be above 1 since
the skydiver is not inputting energy? He/she won't have a rocket up
their butt, will they?
Just curious.
