I love a mystery.

This is a total guess, and open to FACTS, but after some searching, my bet is that Huston was assigned to 30th BG, 819th BS. Consider he was radar and electronics
officer at Wright Field from 1939 to
1943
Then there is this history of the 30th BG and 819th BS :
In September 1943, 134 officers and 1,270 enlisted men of the 30th Bombardment Group's ground echelon left March Field for duty overseas
via Camp Stoneman, California. The first of the flight echelon arrived at Hickham Field, Oahu, Hawaii, on October 1, 1943. The remaining
personnel and planes arrived in Hawaii by October 20. The group's 27th and 38th Squadrons were based at Kahuku, Oahu, while the 392nd and
819th Squadrons were at Barking Sands on the Island of Kauai. The 819th Squadron was the newest addition to the Group. Previously designated
the 3rd Anti-Submarine Squadron, it was redesignated and assigned to the group as a replacement unit for the 21st Squadron that had been sent
to Alaska.
Movement to the forward area began in early November 1943 when the 27th and 38th Bombardment Squadrons moved to Nanomea in the Ellice Islands,
and the 392nd to Canton in the Phoenix Islands. The 819th Squadron remained at Wheeler Field, Oahu, where it processed new crews and airplanes
that were later dispatched to the front line.
In August 1944, the 30th Bombardment Group moved to Saipan where it was joined by the 819th Squadron, bringing together all four squadrons for
the first time since Hawaii.
May be that Huston was assigned for a while due to his radar and electronics experience, and the 819th, previously the 3rd Anti-Submarine Squadron, would likely have all sorts of neat
radar and electronic gegaws in their A/C, but at this point, is just a guess on my part.
