As a young PPL AFI, my first rotary flight was with Dennis at Shoreham in an Enstrom in the late 70's early 80's. I remember him saying he once flew Canberras from Weston Zoyland in Zummerzet.
Even now when doing IF in the areas or flying into Bristol I remember both him and the flight when I look at the disused airfield so it may well be one and the same.
