That's because people don't run supplies! if people weren't too damn lazy to get out of their pretty plane and run an M3 of supplies every now and then it would never have happened that way!
Do you realise how stupid that sounds, or are you trying (and failing) to be ironic? Suicide dweebs used to pork fuel 3-4 fields deep, sometimes more. You would have to practically fly from the HQ fields, to get supplies in. This is a combat flight game, not a cargo hauling game.
Edit for clarification:
I, and others, have run supplies to get fields fully up. People do fly cargo, when a mission went wrong, the hangars were down, someone bombed the wrong target, ect....ect. So don't put out a blanket statement like that, it only shows that you have left the flap on your long-johns undone. I
you for hauling cargo, but thinking no one else does is
