Given the consitions at night time with clouds below to about 7,000 feet and partial clouds and intermittent clouds taken to a ceiling about 4,000 feet, would this present any problems to a jumper? A. There again we're dealing with variables. If a man knew what altitude at the time he was leaving the aircraft, there are two ways to determine his altitude on opening: 1. From the second hand on a wristwatch; 2. A wrist type altimeter. Q. Making this jump, what would be practical for the man to do? To open the chute immediately or to wait until he had a view of the ground? A. I would wait at least ten seconds before pulling. This way I am not only clear of the aircraft, but I am also out of visual sight of the aircraft or any | _ aircraft in the area. Cloud covering is an advantage but not knowing where the ground is,is a problem because of the peaks in the area. The above procedure would be in effect if I was not in familiar territory. Another advantage of an early chute opening would be for the jumper to select the best drop zone possible. In unfamiliar territory and wherein a light might be observed, would’ give the jumper not only an idea of his altitude but an opportunity for steering himself toward a suitable drop zone. In chuting in familiar territory, this type of dropp would be rather "simple to an experienced jumper". This would allow the jumper to "free-fall" for the full : eg a oe ‘ 2 DB Cooper-3377
