Bill Bain it was - Chief Officer, & the Training Officer was Bill Walton. The ATCA was Jim McCutcheon - he was an LAC on a 102 Sq. Whitley shot down in May 1940 & became a Caterpillar Club member after bailing out to become a POW for the duration - & a good bloke he was too :-)
My Watch SATCA at Heathrow, Bob Cook, was a Sergeant with 219 Squadron on Blenheims & is on the Battle of Britain Roll of Honour.
