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.
