This was a daylight precision bombing mission involving 38 planes from the 6th Bomb Group:
The same factory was bombed again on 26 June. The bombload for thirty-eight aircraft was the same [three 4000 pounders each], but two ships were forced to jettison their bombs and five planes hit other targets. Weather again rules out a formation and bombing was individually by radar. An additional 16 per cent of the plant was damages or destroyed, bringing the three-mission total to 26 per cent. Three fighter attacks were reported and one Frank was credited as destroyed by Sixth gunners. All of the Group’s Superforts returned safely.
