In October 1965, 38 squadron (Shackleton MR2s) was moved from Luqa to Hal Far.
I've got a log-book entry:
date aircraft flight details flight time
30th October 1965 WL 740 Transit. Luqa - Hal Far 2 minutes
(We took off from runway 24 and landed on 31)
When I submitted my log book for its monthly signature, the flight-commander deleted the "2 minutes" and substituted "5 minutes" with the comment ; "RAF aircraft are airborne for a minimum of 5 minutes unless they crash" !
