Logbook Trawl
I have been following the thread while on holiday & since returning & checking my logbook I have found the following info re 573.
First flew it on 16 Sqn at Laarbruch on 4 Feb 81 with Dickie A & subsequently for a further 22 sorties, during 81, 82 (last flt 31 Mar 82).
My next encounter with WC was on 12 Sqn at Lossie on 11 Feb 85 (with USAF exchange nav) but suspect it may have been "borrowed" from 237 as it was the only time I flew 573 during my 3 years there.
Then flew her regularly on 237 between 19 Aug 85 & 2 Jun 86 (22 sorties) before a long gap (major servicing at Abingdon??/St Athan?? + assigned to another Lossie Sqn??) to 11 & 12 Oct 88 when I flew her 5 times in 2 days. That was to be my final airborne encounter with WC!
Hope this info may be of use to you.
