I don't think that he ever flew the Short Sunderland, Consolidated Coronado, or Martin Mariner flying boats which were all in service with the UK during WW2. He flew the big Blohm & Voss flying boats so it obviously was due to lack of confidence. There are a number of Japanese fighter types missing from his list and, for the truly pedantic, he didn't fly the CAC Boomerang.

@@IntrospectorGeneral so he only flew 95% :)

@@jlvfr I check the list every few years for additions. A man who flew that many aircraft is bound to forget a few. The Bell P-63 doesn't appear on the 'official' Guinness Records list but is recorded as flown on a day when he flew eight different aircraft types (of the 30 types he flew that month). The list is about 100 longer than when I first read about Eric Brown circa 1970.

Basically, yes

Only one Aichi type, no Avia, Fokker, IAR, Kawanishi or Tachikawa models and, presumably many other aircraft not flown by him. D

It was the intake for the engine coolant radiator.

Yes, pressurised annular radiators. The spinnersbhad internal fans

Also that two wheel landing gear, just like YAK-2/4.

The outsized propellers, the way it seemed to wallow when freewheeling. Not to mention the earlier plainly obvious RC model landing in tall grass.
