Good to see both Alan Pringle and Derek Tuthill look in quite good nick considering both must be 82/83 ish now !
Alan Pringle was at Marham when I was there, but as he was a very long serving and highly regarded pilot and I was young and inexperienced I was somewhat in awe of him, as I was of many others, andnever really got into conversation with them. Then I met Alan again at one of the V Force reunions and found him very chatty and affable. He told me he was one of the tiny number of aircrew who had actually dropped two nuclear weapons. Each crew was only supposed to do one "live" sortie, but when the designated co - pilot on another crew went sick, Alan took his place and thus got to take part in two bombs being dropped.
Interesting accomplishment to have on your CV!
