I just thought about the logisitics of getting out of a tommie.
Unlock the doors (central roof lock)
Unclip harness - (very quick)
Open the door - (This would be interesting above 70knts)
Try and get out the door - (difficult enough on the ground)
Jump
how long does it take a tommie to spin through 4000-5000ft? good luck hitting the silk there, anybody disagree?
