With 9-10 seconds to achieve terminal velocity (+/- 125mph), and allowing an average 2,500 altitude safety cushion -- average free fall time from 12,500 AGL is 60 seconds.
Our college club used to use "standard" above ground altitudes for specific free fall times:
2800-3000' -- "Hop-n-Pop" (5 seconds)
3500' - 10 seconds free fall
4500' - 15 seconds free fall
7500' - 30 seconds free fall
10000' - 45 seconds free fall
12,500 - 60 seconds free fall
All of the above left 2000-2500' which permitted time for a main chute malfunction, cutaway procedure, and reserve chute deployment.
I am not sure how Batman does this with only a cape and no superpowers.... hmmmm
Have a nice day...
