I even (gasp) used to fly a turbine plane without an APU installed, and I survived.
I made the mistake of taking an inop APU on the 300 Guppy in ORD one HOT summer day. Ramp pulled the conditioned air about 10 minutes before dept (contrary to my wishes). The start cart arrived about 5 min after dept (the one that worked anyway). By the time we got the engines and packs going, the cabin temps were triple digit. Waited in an hour long conga line to take off, did I mention it was HOT. Got multiple calls from the FAs about the heat. Never Again. Maybe in the Fall or Winter.
