I had a client who flew the hump, wish I had been more active in talking to him about it.
I didn’t know the USAF carried out air raids from a base in India during WW II but apparently they did

I once talked to a WW II pilot who flew the Hump. He described as always dangerous and often harrowing due to weather, distance, heavy loads, remoteness, forbidding terrain, and operating at the extremes of what the aircraft and navigational technology of the era could do. The effort was necessary though to help keep China in the war against Japan.
I had a co-worker who’s dad flew the hump. He still had his GI issued 1911. The co-worker donated it to a WWII museum.
