Eleven crews flying Martin B-26s take off from England for a low level bombing mission in Holland. One turns back because of mechanical difficulty. The remaining 10 aircraft are all shot down. This mission results in a change in tactics, as from that point on, Marauder crews bomb from medium altitudes of 10,000 to 15,000 feet where they will suffer only light losses to anti-aircraft fire.
