I don’t recall that flight being in his log book, but I will check.

He did, however, fly comparison flights against the Me 109-E in early 1940 although FFYL states he also flew the 109 on that occasion. His Log Book and other sources say not.

PS – been scrabbling around to find my copy of Tuck’s Log Book – it must be in the loft. From memory the flight in question was with AFDU and, I think, on 8 June 1940.
