Gp Capt SMO at the Towers '63 time was also pilot qualified, as was Goeffrey Dhenin who flew a Canberra though at least one of the nuclear test clouds and went on to be an Air Marshal. Oddly, called in at a small French airfield (Pons-Avy) one day and got talking to a guy there, turned out to be Dhenin's son in law
