Plot hole: One of the flying dragons impacts the right outer engine of the B-29, and the fire spreads to the right inner engine. The crew lands the plane on the island, and the girls rebuild both engines, despite the fact there are no parts available on the island.
Plot hole: Needing more fuel to get to Tinian, the crew recovers some 55 gallon fuel drums from the beach. These drums weigh in excess of 400 pounds, yet one guy and one girl hoist them into the truck with little effort.
