Air India Annapurna
Crashed while landing in Bombay, 22nd June 1982
ISC 82-50: State Bank of India, Amritsar, registered letter of 21st June, is purported to be on the Annapurna when she crashed while landing in Bombay from Madras on 22nd June. This is highly unlikely.
 
There is an inventory report by Senior Superintendent, Air Mail Sub Division, Delhi which says that the letter was returned by Inward Section, London as received damaged, and Delhi station, then carried out an inventory, and sent the letter along with original contents and inventory report back to the UK on 1st July 1982 in an ambulance cover.
 
Should not be an Annapurna crash recovery cover, but an interesting postal article nonetheless.
