Mission 115.

B-24D serial 41-24121 was assigned to the 330th Bombardment Squadron, 93rd Bombardment Group, operating from Site No. 7, Benghazi, North Africa. The aircraft was lost on August 1, 1943, during the low-level raid on the Ploesti oil refineries in Romania — one of the most costly missions flown by the Eighth and Ninth Air Forces during World War II. The aircraft was lost as a result of a mid-air collision with another aircraft identified in the report as "MACK 334." The last known position was recorded at approximately 41°55'N 23°30'E, placing the aircraft over Bulgaria at 1330 GMT. The collision occurred roughly one hour after the crew had left the target. The aircraft carried a crew of ten plus one passenger, F/O Nelson R. Collins. Weather at the time included heavy cumulus clouds. Six crew members perished in or as a result of the collision, three survivors bailed out over Bulgaria, and one gunner (Pearson) bailed out but was killed when his parachute collapsed. Bulgarian Army personnel confirmed Pearson's death and his personal effects were later seen in Sofia. The aircraft struck the ground in mountains southwest of Sofia, Bulgaria. The wreck contained the bodies of the pilot, co-pilot, navigator, bombardier, engineer, and radio operator, all of whom were likely killed in the cockpit and nose section during the collision. The Missing Air Crew Report was prepared on August 12, 1943, and transmitted to Headquarters Army Air Forces by the Ninth Air Force on September 13, 1943.

The aircraft was lost on August 1, 1943, during the low-level Ploesti mission (Operation Tidal Wave), departing Benghazi at 7:30 AM. The plane sustained catastrophic damage, with the left wing torn off and engines No. 1 and 2 knocked out, leaving it out of control. The plane crashed on a mountainside in Serbia at approximately 4:45 AM (likely local time after a long flight) and was burning fiercely upon impact. Only three enlisted gunners successfully bailed out; the mountain police informed S/Sgt. Murray after his capture that the rest of the crew had been killed. Murray examined the wreckage and confirmed the aircraft was destroyed on the mountainside. The plane did not explode on striking the ground, though it burned fiercely. All parachutes of the three survivors opened successfully; Murray's chute opened just above the treetops.

The aircraft took off from Benghazi at 07:31 on August 1, 1943, on a bombing mission. The plane went down over Bulgaria at approximately 5:00 PM. S/Sgt. Koen bailed out at approximately 2000 feet along with the two waist gunners and the tunnel gunner; their parachutes opened. The plane did not explode on impact but caught fire and burned. After reaching the ground, Koen observed two men who had been thrown from the plane without parachutes. Seven crew members were subsequently buried, believed to have gone down with the plane.
