A beautiful launch! the carrier radios the bal loonists. Four gunlike squibs, firing simultaneously, sliced the tie-downs holding the gondola to the deck, and now the envelope leaps skyward past a tiny weather balloon. Dangling sleevelike line at right holds electric wires attaching gondola to helium valves. Para chute connecting cage and balloon will open auto matically in an emergency.
