thanks for the replies & PMs - please do contact me if you or someone you know flew in the first few days of the air war.
& regarding the "LL losses" - this has been a much-misunderstood part of GR1 history. I'm sure someone has all the facts at their fingertips regarding the exact (or presumed) cause of each loss, but I can think of 2 of my fellow POW chums who were lost/shot down at medium level.
& certainly a number (majority?) of the US losses were medium level too.
Anyway, perhaps we will discuss it 'live' during the programme!
