When they were evacuating Tunisia, they apparently stuffed two ground crew men in with the pilot. One of the pilots (Ernst Reinert) got into a dogfight over the Med and managed to shoot down the allied fighter even with the two extra guys in his plane.
It looks like the final evacuation took place about May 8, so I’m a bit early with this.
With two extra guys throwing up in his plane, no doubt.
