misdrop

To drop (especially, to airdrop) incorrectly or in the wrong place.

Nine C-47s from the 53rd Transport Command Squadron had managed to misdrop the entire Headquarters Company of the Third Battalion along with 55 equipment bundles containing machine guns, mortars, ammunition, rations, maps, demolitions equipment, and medical supplies. Sometime after 2:38 AM on June 6, Captain Leroy Brummitt, first man of his stick of paratroopers, found himself lost and alone.

An incorrect or misplaced drop (especially an airdrop of bombs, supplies, or paratroopers).

Much conjecture has arisen about the reasons for the misdrop. The pilots had been given plenty of flying time to become familiar with the C-46, but the opportunities to fly in tight formation were somewhat lacking. This may well have been one of the reasons for the milling about as the aircraft approached the Rhine.
