"THE P-38 IS NOT A BOMBER! /stomp feet"
Some P-38s
were flown as bombers. The lead P-38 was fitted with a 'glass' nose, carried a bombardier and a Norden sight, and was known as a 'Droop Snoot'. The P-38s flying formation on him released their bombs when they saw his go, the same 'drop on the lead bomber's signal' procedure as used by the big boys.
The last place I'd look for historical veracity would be the History and Discovery channels; the commentary is all too often uninformed, inaccurate, 'gung-ho' drivel and the film editors haven't a clue.
