For Alec & KenWW ...
Basil Dodd was indeed a graduate of ETPS.
He started an RAF exchange tour in 1964 flying the CIA operated Lockheed U-2 (80' wing span J-75 powered C, F, G (carrier), & H models).
On his return to the UK he went back to RAF test flying and thence to the UK CAA.
A quiet gentleman.
The two pictures show him (1) in the Mojave Desert near Edwards AFB & (2) undergoing a test at Los Alamos, NM. This test was a small part of the week long medical then given each year to all U-2 pilots
