Army Air Force (USAAF) as B-24J-5-CO Liberator serial number 42-73052 and converted to a F-7A photographic reconnaissance version. Painted in a blue color scheme. Flown via Hickam Field then across the Pacific to Australia. On March 25, 1944 arrived at Garbutt Field near Townsville.

Assigned to the 5th Air Force (5th AF), 6th Photographic Reconnaissance Group (6th PRG), 20th Combat Mapping Squadron (20th CMS). Nicknamed "Under Exposed!" with the nose art of a blonde woman removing her bra atop a circular background.

On April 2, 1944 took off from Garbutt Field at 7:45am on a flight northward to Port Moresby. On April 3, 1944 departed Port Moresby at 8:30am on a flight to Nadzab Airfield arriving at 10:00am. This aircraft flew photographic reconnaissance missions photographing enemy targets in New Guinea and the Netherlands East Indies (NEI). In late May 1944, the paint was stripped to a bare aluminum finish.

Mission History
On May 22, 1944 during the early morning took off from Nadzab Airfield piloted by 1st Lt Loren G. Barstow as one of three F-7s on a photographic mapping mission over Padaidori Island. This was pilot Barstow's second combat mapping mission. Ten minutes after take off, this B-24 observed circling to the northwest of Nadzab over the Markham Valley at an altitude of about 5,000'. At approximately 4:00am, this F-7 crashed into Mount Wilhelm at an altitude of 13,000' killing the entire crew. When this aircraft failed to return it was listed as Missing In Action (MIA).

The wreckage of this B-24 remains on Mount Wilhelm in the vicinity of Keglsugl.

Chris Breuer reports:
"The terrain is very rocky so the plane has been destroyed along with all the things that have been stolen from it in the past years."

Recovery of Remains
The entire crew was officially declared dead the day of the mission. After the crash, Ralph Bowley, 20th CMS intelligence officer trekked to the crash site and recovered the remains of the crew to Nadzab for burial at Nadzab Cemetery.

Lt. Col. David W. Ecoff Sr. (pilot of the 20th CMS) recalls:
"The remains of the crew were recovered by Ralph Bowley, our Intelligence Officer and buried at the Nadzab Cemetery with honors."

Postwar, the remains were transported to the Philippines and United States for permanent burial.

The entire crew was officially declared dead the day of the mission and earned the Purple Heart, posthumously.
