In 1957 I was sent on my first solo in a glider at St Athans by Lt Cmdr Brett-Knowles RN. - Pulse 1
Don't know your chap (try Union Jack ?) - Danny
Sadly neither do I, especially since he certainly seems he seems to have stood out from the crowd - and quite a bit before my time too!
However, I note that he was actually an Instructor Lieutenant Commander with seniority of 16 July 1952, who would therefore probably have been in his late 30s in 1957 when he sent Pulse1 soaring solo skywards.
By implication in view of his gliding skills, as a member of the Instructor Branch/Specialisation (broadly equivalent to the RAF Education Branch), it sounds as if he almost certainly would have been someone who had sub-specialised as a Met Officer, the duties of which were carried out by Instructor Officers prior to the much later formal establishment of the Meteorological and Oceanographic (METOC) sub-specialisation.
Meanwhile, back at St Athan ......
