Naval Academy, jet units which reduce normal takeoff runs from 33 to 60 percent or allow for an increase in leads are soon to be installed on Navy aircraft. Of particular value on the restricted areas of carrier flight decks, JATO as jet-assisted takeoffs are known in the Navy will also be extremely useful to aid heavily-laden flying boats up from the water. Resembling bombs except that they are affixed to the fuselage of planes rather than under the wings or enclosed in bays, jet units contain solid propellant, which includes oxygen, and are ignited by electrically-controlled spark plugs. The escaping stream gives the plane its 'thrust.' Doubly-powered by the flow of jet units, a Navy Vought Corsair fighter plane roars down the deck of a carrier for a takeoff.' 9 September 1944
