My late Father was on 623 GS at Tangmere from end Sep 1963 to end Jul 1968.
Looking at Dad's Log Book it seems that Flt Lt Rogers was CFI at end 1965 through to Jan 1968.
They flew together on:
8 Mar 1964 in T21 WB932 Circuits/Mutual, 2 launches, 7 mins
4 Apr 1964 in T21 XN248 Mutual, 1 launch, 5 mins
19 Sep 1964 in MkIII WT900 Air Test after rebuild, 1 launch, 3 mins
27 May 1967 in T21 WB919 Mutual, 2 launches, 10 mins
Unfortunately the only character I remember from that time (I was rather small!) is Bill Verling but I don't know if he is still with us.
Sadly Dad died back in 2005 so I can't ask.
