Sikkim is the first country in the world to successfully dispatch by means of a rocket, a parcel containing small quantities of such useful articles as medicine, tobacco, tea, sugar, etc.
World’s first parcel dispatch over the river was done on April 10 over River Rani khola that is written as Ranikhali on the covers at 3.30 pm. CE Dudley discharged the mail rocket.
The sixth firing on April 10 at established a new world record when for the first time a parcel was carried by means of a rocket. The parcel included 12 items that had packet of tea, sugars, spoon, hanger chief, toothbrush, cigarettes, and others.
The rockets were apparently fairly crude, resembling larger versions of fireworks. They were approximately 6 feet in length with the body (which carried the mail) 2 feet long. They were launched by lighting a touch paper from a sloping stand aimed in the general direction of the intended target. Oriental Fireworks Company based in Calcutta provided all the rockets to Smith. “The rockets were launched by lighting a touch paper from a sloping stand aimed in the general direction of the intended target”,
