My father's last flight in a Heyford was on March 3rd 1939; he flew with F/O Robertson from Mildenhall (149 (B) Sqn) to St Athan, and back again on the same day with F/O Fulton. He had converted on to the Heyford in January 1938 after completing his Advanced Training at No 2 FTS. I have a picture somewhere of his Heyford at Mildenhall after a solo flight (maybe this first in that aircraft), fuselage and tail pointing skywards, nose section flat on the ground, the empty seat sliced in two by a propeller. I suspect he braked too hard, but it's only a guess.
He then went on to intensive training on Wellingtons, still with 149(B) Sqn, culminating in the Brunsbuttel raid on September 4th.
I always thought the Heyford had a crew of 2, Ist and 2nd pilots, sitting up there in the open cockpit. Was it really 6, as per the post above? What did they all do? Where did they sit?
