Did he comment on which planes he loved flying, tolerated flying or hated flying?
Offhand the only airplane I heard a negative comment about was the Bf 109G-12(?) two seat version at Gablingen. He basic observation was that it was the worst vision of any aircraft - ever - for him. He flew about 70 different types and rated in 30. He never flew any of the Navy ships but flew every fighter in US inventory from P-38/39/40/47/51/61/63/ through F-80/82/84/86/86D/89/94 through F-100&105 plus Bf109G-6/12, FW 190A-8 and D-9.
A-20, B-25, B-26, A/B-26, plus SA-16, B-17, B-29, B-47, B-57, T-6, T-28, T-33, T-37, T-38.
SA-16, C-46, B-17, B-29 & B-47 as co-pilot.
All the BT's, C-45, C-46 and C-47
F-86E was his favorite, Bf 109 least favorite. P-51B/D before Reverse Rudder Boost and F-105 were close seconds to the F-86
5500 hours PIC
EDIT - he was not fond of the C-46 citing displeasure at smelling gas fumes all the time.
