That's interesting - I was flying out of BOG a few years ago on a 757 with inop APU and there was some trouble in finding two carts needed to start the engine, and then some doubt as to whether the ones they found would put out enough air pressure to get the engine started.
At least we didn't have to worry about cabin temperature. Despite the evening temperature being 50F every day they still managed to make every aircraft feel like 90F nearly every time at BOG so it didn't actually get any hotter while we were hoping they'd get the engine started!
