GCA
Being on the last Nasho Aircrew intake in 1957 I had the opportunity to stand behind the pilot with a headset on and listen to 2 GCA let downs at East Sale in a Dakota one night after a trip from Laverton. Both let downs were to "round out, hold off, hold off, touchdown, touchdown, "Now"
Amazing how accurate both landing were!" Convinced Me!
I can remember being told it would never be adapted in Civi Street as the pilots would not hand that much control to someone on the ground!
