I knew Dave as a Flt Lt in my early years as an ASOp at Buchan before escaping onto IOT & beyond. Although it was many years ago, his name is etched in my memory as one of the very few good guys I worked for & I won't forget how much he stood up for the junior airmen in the face of some very pompus Sqn execs on more than one occasion.
Very tragic news, my thoughts are with his family & relatives during these dark hours.
RIP Sir.
Per Ardua.
