P-38F "Dumbo!" 42-12847 Nose Number 37
Assigned to P-38F "Dumbo!" 42-12847 #37, with crew chief Ray Chartrey
(now deceased). Flew a number of his 151 missions in this aircraft. All the 39th pilots gave him the nickname of 'Dumbo', which he named his plane.
The nose art was a pink baby elephant with wings, about 3 or 4 feet high, which
Dunbar painted himself as an enlargement of the Disney character "
Dumbo", the flying elephant. He drew dust puffs and nuts and bolts trailing
his path and a big "DUMBO!" call in front. Dunbar had experience
drawing enlargements of comic page shadow drawings like "Prince Valient".
On September 2, 1943 on his off-duty flying day, his diary
notes that the plane crashed at Terapo with one of our newly assigned pilots,
Hamilton Laing. Landed with propeller out and low on gas. With the help of natives
he returned unharmed to base at 14 Mile Drome (Schwimmer). Dunbar was assigned another
P-38, #37 and continued missions. On Nov 7, 1943, another new pilot,
Al Quinones, was assigned to fly his aircraft P-38H 42-66911 on a mission over Rabaul mission (his 7th mission)
as Dunbar departed for leave to Sydney. That mission, Quinones was shot down from the middle
of the formation, bailed out and became a Prisoner Of War (POW) at Rabaul and survived captivity.

JD-1, B-29, C-97, CH-46, CH-47. Work entailed development of inertial guidance
systems, flight control, navigation systems, weapons aiming (air to air gunnery),

Wreckage of "Dumbo!"
In October 1980, Bruce Hoy (former PNG Museum modern history curator) revealed to him that the wreckage of P-38F "Dumbo!" 42-12847 #37 force landed at Terapo Airfield remained in situ. Hoy gave Dunbar a color picture of
the wreckage. Hoy made a business trip to USA soon after and visited Dunbar's
home to give him a souvenir from the plane, one of the machine gun blast tubes. He
has it displayed in his office with other mementos.
