Eric,

the forces are all the same.

there is no difference in forces strengths launching to 1000ft or to 5000ft
the applying forces just last longer thats all.

I agree with that, but what I asked about was the rate of climb (fpm =
feet per minute):

Surely the cable tension must be greater to provide a 3500 fpm launch
instead of a 1000 fpm launch?
