40 second delay time. This would put him at approximately 2,000 feet altitute when the chute opens which still gives him another three minutes to the ground.

Footwear for an experienced jumper is inconsequential.
Jumping into a heavily wooded area is also relatively simple.
Jumping into water is even more simple for an experienced jumper.
Q. If the wind velocity at 10,000 feet was 25 knots and the ground level five knots, roughly how far could he travel?
A. He would be in the saddle for ten minutes. On a clear and pull situation (immediate opening of the chute), he could go five miles on the wind line or wind direction; and a normal delayed opening maximum distance with a five knot wind would be two or three thousand feet. Even with a non-steerable chute, by taking hold of the risers and facing into the wind and making an almost direct descent which would also produce a very soft landing equivalent to stepping off a chair.
Q. Would the spped of the plane at 178 knots present any problem?
A. No, not for a jumper.
Q. Based on the information we have discussed, here, does this jump present any problem to an experienced jumper?
A. None whatsoever.
Q. Do you think this man made this type of jump before.
A. I would say he has made some high altitude jumps before. The mere fact that the jumper requested 15 degree flaps and gear down to increase drag would also indicate the jumper was an experienced high altitude parachutist.
