exploded, though most of the smaller second cargo, which included survivors of the first flight, was saved. Stephen Smith, a Secretary of the Indian Airmail Society, combined his work with his interest in rocketry. His first launch was on 30 September 1934, and he experimented with 270 more by 4 December 1944. 80 of these contained mail, and his achievements include the first successful rocket mail sent over a river and the first rocket to carry a parcel. The Oriental Fireworks Company supplied Smith with 16 rockets between 23 March 1935 and 29 June 1935. Between them, these "Silver Jubilee" flights carried over a thousand event covers. In 1992 the Indian government issued a stamp to celebrate the centenary of Smith's birth, calling him "the originator of rocket mail in India". United States One of the first successful deliveries of mail by a rocket in the United States was made on 23 February 1936, when two rocket airplanes that were launched from the New York side of the frozen Greenwood Lake landed on the New Jersey side, less than 100 yards away. This event was preceded by several other successful rocket mail experiments in the early 1930s. During the mid-1950s, "amateur" rocketeers flew a number of zinc dust / sulfur "micrograin" solid propellant mail-carrying rockets interstate, from California, across the Colorado River, and into Arizona. The postal covers were printed for each occasion, and franked at the nearest destination post office. In 1959 the U.S. Navy submarine USS Barbero assisted the Post Office Department, predecessor to the United States Postal Service (USPS), in its search for faster mail transportation, with the only delivery of "Missile Mail". On 8 June 1959, Barbero fired a Regulus cruise missile – its nuclear warhead having earlier been replaced by two Post Office Department mail containers – targeted at the Naval Auxiliary Air Station at Naval Station Mayport in Florida. The Regulus cruise missile was launched with a pair of Aerojet-General 3KS-33,000 [3 s duration, thrust] solid-propellant boosters. A turbojet engine sustained the long-range cruise flight after the boosters were dropped. Twenty-two minutes after launch, the missile struck its target. The USPS had officially established a branch post office on Barbero and delivered some 3000 pieces of mail to it before Barbero left Norfolk, Virginia. The mail consisted entirely of commemorative postal covers addressed to President of the United States Dwight Eisenhower, other government officials,
