On 4 January 1944, AAF pilot, 1st Lt. Pachanian was flying an O-47B (#39-770) with his observer and gunner, when it engaged a Marine F4U-1 (BU 17-812) flown by Major Delbert W. Burke from VMF-225, MAG-23, out of Ewa Field, MCS. Major Burke was part of a scheduled gunnery mission when it was engaged by the two O-47Bs. Apparently, one O-47B and the F4U-1 had a mid-air collision, with Major Burke's aircraft exploding approximately 4 miles south of Barbers Point, Oahu. Major Burke's remains were never found."
