Five or six in-country flights on Indian Airlines. (Not Air India) That was the year it qualified for most-disaster prone airline in the world according the the NY Times article I had in my suitcase. That was also one of the times the Indian Airlines offices in Bombay were bombed a few days before we arrived.
I must say the flights were fine, once you got used to the guards armed with machine guns searching the plane at each stop. Great security. I was an oblivious tourist and have no idea what was going on.
