[REDACTED], Minneapolis, called on 11/29/71.

1. He said that 90% of the skydivers are licensed by the U.S. Parachute Association, P.O. Box 109, Monterey, California. The license has a photograph of the individual; however, he does not believe that the association maintains these photos although they do maintain descriptions.

2. Northwest people have discussed this jump with a pilot who has made 500 parachute jumps, including two at night. He said that with a lighted target, a man could come within 1000 feet of the target from the height that they were flying on the night in question, and that you could guide yourself as much as 45 degrees in either direction with a plain survival type parachute, if you had the knowledge.

3. He stated that theyhave been passing information on to us based on the "pressure bump" indicating that the man had jumped north of Portland. He said it was entirely possible that the man did not jump when this "pressure bump" took place. It was entirely possible that he sat on the end of the stairs to check out his reference points before he jumped. If he did this for even a short time, he could have easily landed across the river in Oregon.

He pointed out in this connection that there is Aurora Field near Donald, Oregon.
