Andy,
it was non-ops sortie. On 26 June 1941 Spit IA R6709 (code RY-R) was flown by P/O Karel Kasal of No 313 (Czech) Sqdn from Catterick to Martlesham Heath (via Duxford) for visit friends from No 310 (Czech) Sqdn. Totally drunk he made unauthorised aerobatics over the Martlesham Heath, crashed on landing and hit a Hurricane IIA (possibly Z2768 NN-H). Kasal was injured in the head and taken to hospital Ipswich.
R6709 - Cat. E,
Z2768 - Cat. B (according different sources AC).
Interesting detail: Z2768 was later sent to Russia under Lend-Lease Act and was shot down on 21 Jan 1943 by German Ace Lt. Rudi Müller of JG 5. Soviet pilot 2/Lt Boris Lazarev of 760. IAP was killed. Wreck of this Z2768 was found in Karelia during 1999 and now is again in Britain for repair.

Andy, let me know off-line, please, if you received my "Czech 1941" images.
