The captain on this aircraft shut the engines down before we could get the tail post in and there were some concerns that it might sit on it's tail as the passengers moved aft to deplane. However the passenger door jammed on top of the steps (and the hinges didn't snap) so everything was OK. DC-4's were very nose heavy when empty and very tail heavy when fully loaded. When loaded, the tail was so low we couldn't get the tail post out. We had to wait for the engines to be started to lift the tail enough to remove it and put it in it's stowage in the rear hold before closing the hold door. Most of my white uniform shirts had black spots on them from the oil thrown out by the engines!
