World's 1st Parcel Rocket Dispatched was done in Sikkim in 1935

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 3.35 pm 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. Dudley fired the parcel rocket over the river Rani khola from Surumsa to Ray. On the parcel reaching destination the river was crossed and Smith opened the parcel. All the articles were perfectly intact. In the missives of word “mail” was canceled by hand and the word “Parcel’ written instead.

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”,
