Dick Bennett, in his mission log book that he called the "Llittle Blue Book", hand-wrote notes in 1992 about the demise of the 'Til Then, on 18 May, 1945, in one of the most dramatic crashes on Angaur. He notes that a "minimum crew" of men from Crew #39 (Co-pilot Fritz Johnson, Lee Colvin, and Dick Bennett (it is unclear if Turek was aboard, but reportedly so), were on a flight evaluation of Dubinsky's Co-pilot, 1st Lt. Rudolph Flanagin. Two marines went along for the "joy ride". Other sources (including the 494th Group History, Vol. II) stated that the co-pilot being checked out in 'Til Then undershot the runway, had a disastrous crash that totaled the plane, however, no one onboard was seriously injured. Lt. Flanagin continued to fly subsequent missions and was promoted in rank from 2nd Lt., so the cause of the crash seems to have been mechanical (or less likely weather) in nature rather than pilot error attributed to Lt. Flanagin.
