Aircraft History
Built by Lockheed Aircraft Corporation (LAC) in Burbank, California. Delivered to the U.S. Army. Disassembled and shipped overseas and reassembled.

Wartime History
Assigned to the 5th Air Force, 8th Service Group, 301st Airdrome Squadron. No known nickname or nose art. When lost, engines V-1710-89, V-1710-91 serial number 42-93062 and 42-92801.

Pilot History
Gronemeyer was a bomber tail gunner with the 28th Composite Group, 73rd Bombardment Squadron in the Aleutians during September 25, 1940 until October 6, 1942 when he reported to Flight School. Afterwards, he was assigned to the 5th AF, 475th Fighter Group, 431st Fighter Squadron on June 23, 1943. He flew 500 combat hours on 135 missions in New Guinea and Philippines.

Mission History
On December 31, 1944 took off from Nadzab Airfield No. 1 at 13:15 hours with three P-47s. At about 1330, the formation leader climbed to 17,000' to avoid weather in the Tsili Tsili area. At 1335 hours, this aircraft left the formation and headed for a small valley, still climbing. He was called to rejoin the formation, but no reply was received. When last seen, the aircraft was still climbing on a heading of 220 degrees at approximately 1345 hours. It is believed this P-38 was not carrying oxygen during this flight. Lost roughly 17 miles south-southwest from Tsili-Tsili over the Banir River.

On November 2, 1980 this aircraft was located by Richard Leahy and David Pennefather. During early November 1980 a team from US Army CILHI visited the crash site and recovered a small number of bones.

Richard Leahy adds:
"This MIA site is actually the first that I can claim responsibility for locating. Both the pilot and his piggy back passenger were recovered. Located ten miles south west of Marilinan. He was on his way from Nadzab to Moresby. He had a passenger as well. This aircraft was being flown by Capt. William Gronemeyer, an experienced pilot who was on his way out on R&R at the time. I have often wondered what happened to him. The flight from Nadzab to Moresby is not a difficult one at all, especially in a high powered ship like a P-38. WWII pilots have told me that the gyro instruments they had in those days were notoriously unreliable. He also said that pilots were expected to remain visual, that they received an absolute minimum of instrument training. I have a set of photographs of this site taken by CILHI at the time they made the recovery staging out of Engati. "

Gronemeyer and Springer are buried at Fort Snelling National Cemetery in a group burial at section A-14 site 2806.

Mark Gronemeyer (nephew of William Gronemeyer):
"He rose to the rank of Captain and received 7 Air Medals. His plane crashed trying to cross New Guinea on New Years Eve 12-31-44 to attend festivities. The plane was found with the Assistance of Richard Leahy on November 2, 1981. Gronemeyer and Springer are buried at Fort Snelling, MN. I sent extensive information for Possum, Clover & Hades History of the 475th FG in WWII and historian for the P-38 Museum."

Bruce Hoy Diary 11 November, 1980: "Tuesday, drove out to the airport at 8.00am and met the CIL‑HI team arriving from Lae. I gave them the appropriate export certificates covering the remains collected from P-38H 42-66562, A-20G 43-21416 and C-47 42-24215."
