note on first airmail serviice in India?

Answer 1

From Wikipedia:

Indian Postal Service functioning under the brand name India Post, is a government operated postal system in India; it is generally referred to within India as "the post office".

The Indian Postal Service, with 154,000 post offices, is the most widely distributed post office system in the world (China is next, with 57,000[2]). The large numbers are a result of a long tradition of many disparate postal systems which were unified in the Indian Union post-Independence. Owing to this far-flung reach and its presence in remote areas, the Indian postal service is also involved in other services such as small savings banking and financial services.


Good Luck....
