OXYGEN EQUIPMENT
TEST IN PARACHUTE JUMP
Rec. 9 a.m. WASHINGTON, July 1. Testing special self-developed oxygen equipment, Lieut-Colonel William Lovelace, making his first jump, parachuted from 40,200 feet, one of the highest recorded—perhaps the highest—with an immediately opening parachute. The drop of 7.61 miles occupied 23mm 51sec, through temperatures 50deg below zero. The equipment comprises a small cylinder sewn into the clothing, and containing a 12 minutes' supply of oxygen. Speed is essential, because at 40,000 ft unconsciousness occurs within 15 seconds without oxygen, and the special supply must last from the time the flyer disconnects his regular mask, prepares to bail out, and hurtles through the oxygen-thin air. The War Department said that Colonel Lovelace suffered no ill effects except a frozen hand when a'glove was torn off. •
Colonel Lovelace is a former president of .the M,ayo Clinic, and in 1941 was co-winner of the Collier trophy for aviation medical research.
