An unanticipated face-off
Suddenly, the crew of the B-17 was in a desperate battle for their life, as they were being raided by half a dozen hostile planes. They were supposed to release their cargo as they flew over their intended target, but something went wrong with the compartment doors, and they couldn't. As a result, they had to make a big circle and start over. Ultimately, they were victorious, but Japanese planes were already battle-ready by that time.
