[REDACTED] the information of Seattle, on 12/16/71 [REDACTED] pointed out that on the flight records from Elsinore all the altitudes of jumps made were from 2,500 to 12,500 feet. He explained that sport jumpers and parachute enthusiasts all jump from altitudes in multiples of 1,000 starting from 2,500, 3,500, 4,500 etc., with the exception of 2,800 which is the competitive height for target jumping. He stated that the 10,000 foot level is reminiscent of Air Force training. He referred to Air Force phamphlet number AFP 160-10-3 entitled "Your Body in Flight" which places 10,000 feet as the maximum altitude considered safe without oxygen. [REDACTED] surmised that a man with Air Force experience may be the type of person that should be considered a suspect.

On the other hand, he pointed out that parachutists have different classes of licenses, A, B, C and D class licenses. To hold a D license a jumper must make two night jumps as well as other qualifications. A person with a D license is an experienced jumper.
