Official Caption: "Rome. 6/8/45--Jump bottles--A new stream-lined oxygen bottle assembly which recently has been approved by the U.S. Air Forces allows parachute jumpers to bail out from altitudes as high as 40,000 ft. (12,000 Meters) with the assurance that their oxygen supply will stick by them until they touch ground. Tests made with the new 'H-2 Bail Out Assembly' show that it is better than any former 'Jump Bottles'. It plugs right into the standard oxygen mask which affords protection against frostbite and hailstones after jumping. The most important improvement is that the capacity of the H-2 has been increased from 20 to 22 cubic inches (330 to 360 cubic centimeters), an extra margin that can mean everything when an airman steps out into thin air.--PWW Photo--Serviced by Rome OWI.
