My Father was taught to fly at Hanworth in 1938 on Blackburn B2's (one of which is still at Old warden). I have some photos of B2's lined up outside the Hanworth house and a course photo which I think is next to the House. My Dad ended up flying Spitfires from Heston in September 1940 with the experimental Photo Reconnaisance Unit PRU. There is a good 1938 aerial photo of Heston taken from the northwest
Heston Airport Image from the AirTeamImages Picture Library
I think the M4 now cuts across the bottom left hand corner of the phot.
My father is now dead, but does anyone know where the PRU was based at Heston?
