Gentlemen,
While this is surely an exception, it may demonstrate how difficult a P-38 was to fly. On August 24th 1943, 6 pilots with no twin engine time, and about 70 hours each in advanced P-40 training (training time in the States, not combat) were assigned to fly P-38s of the 27th Fighter Squadron, 1st Fighter Group. The pilots were 1st Lt Jim Alford, (a former flight instructor) and 2nd Lts. Eldon Vondra, Merle Brown, Frank Gerry, Francis Lawson, and Walter Flynn. A combination of circumstances lead these pilots being posted to the group. First, the P-40 squadron that these 6 were to be assigned to was deactivated. Second. The 1st Fighter Group needed pilots to replace the ones that they lost. Third, none of the 6 wanted to be assigned as co-pilots on some multi engined aircraft. Finally, Alford knew the officer in charge of making assignments. In war, the rules aren't always followed. Lawson flew 6 training flights starting on August 26th and then his first combat mission on Sept 5, 1943.
As a follow-up, the fates of the 6 pilots with final (?) ranks and scores:
Lt Vondra KIA 12/1/43. His score was 1 destroyed, 0 probable, . 5 damaged.
Lt Brown POW 3/29/44. His score was 1 destroyed, 0 probable, 1 damaged.
Lt Gerry POW 6/13/44 His score was 3 destroyed, 0 probable, 2 damaged.
Capt Lawson Competed tour. His score was 2 destroyed, 0 probable, 1 damaged.
Capt Flynn Completed tour. His score was 0 destroyed, 0 probable, 1 damaged.
Capt Alford Completed tour. His score was 2 destroyed, 0 probable, 1 damaged.
Vondra was lost in a running dogfight with 15-20 enemy aircraft while flying a P-38G.
Brown was shot down by enemy fighters while flying a P-38H
Gerry was lost on an escort mission while flying a P-38J.
The above does not really prove if a P-38 was easy or difficult to fly. However, the above does point out that at least 6 pilots with no twin engine training were successful with it.
