On 30 September 1934, he launched his first mail rocket, using a rocket made locally by the Orient Firework Company of Calcutta. The flight was a ship-to-shore launch, The rocket carrying 143 covers, left the D.V. Pansy and exploded mid-air scattering the mail over the sea. 140 covers were recovered and taken to the
Sagar Lighthouse, where the keeper postmarked the mail. This was followed by: shore-to-ship, night, and miniature newspaper flights. Smith's flights in Sikkim, a British Protectorate in the eastern Himalayas, received official sanction from ruler of Sikkim,
Tashi Namgyal. Here he carried out 20 successful rocket experiments and achieved the first rocket parcel mail. 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 covers. Smith made history once again, when he used his rockets to carry a food package across a river to the Quetta region, which had suffered an earthquake. The package contained: rice, grain, spices, biris (Indian cigarettes) and 150 rocketgrams. ==Achievements==
