“The hump” was a military aerial supply route from Northern India to China, over and through the Himalayan Mountains, that allied pilots flew during WWII.
It was, and is, widely considered to be one of the most harrowing and deadly flights in aviation history.
I recall reading one airman’s story of watching two planes explode right in front of him. Twenty of his friends died within minutes of each other. This was on takeoff.
The most notable plane that flew the hump, the Curtiss C46 Commando, had nicknames like the “flying coffin,” the “plumber’s nightmare,” and “Curtiss Calamity.”
On board, oxygen was scarce, and temps were freezing. The survival stats are staggering, and not in a good way.
In the end, because of the hump pilot, the allies held.
