Mission History
On December 31, 1944 at 1:15pm took off from Nadzab Airfield No. 1 piloted by Captain William C. Gronemeyer with passenger 1st Lt. Charles W. Springer on a cross country flight bound for Port Moresby. The flight was led by Captain Glenn Perryman with three P-47D Thunderbolts plus this P-38 Lightning.

The weather was 4/10 to 6/10 cumulus and stratocumulus clouds with 12 miles of visibility. At about 1:30pm, the formation leader climbed to 17,000' to avoid weather in the Tsili Tsili area. At 1:35pm, left the formation and headed for a small valley and was still climbing. This aircraft was called to rejoin the formation, but no reply was received. Last seen at approximately 1:45pm climbing on a heading of 220° roughly 17 miles south-southwest of Tsili Tsili over the Banir River. It was believed this P-38 was not carrying any oxygen for the pilot or passenger. When this aircraft failed to return it was officially listed as Missing In Action (MIA).

On November 2, 1980 this aircraft was located by Richard Leahy and David Pennefather.

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."

Recovery of Remains
During early November 1980 a team from US Army CILHI visited the crash site and recovered a small number of bones. Afterwards, these remains were transported to Hawaii and were identified as the remains of both individuals.

Richard Leahy adds:
"I have a set of photographs of this site taken by CILHI at the time they made the recovery staging out of Engati."

Both crew were officially declared dead the day of the mission. As the mission was deemed non-combat, neither earned the Purple Heart, posthumously. After the recovery of remains, Gronemeyer and Springer were buried at Fort Snelling National Cemetery in a group burial at section A-14 site 2806.

Springer also has a memorial marker at Oakwood Cemetery in Rochester, MN.

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."
