Prior to being an instructor with 621 VGS, Flt Lt Rigsby had been an instructor with 625 VGS for a number of years as CGI through to Flt Lt, attaining A2* senior instructor grade. Whilst still carrying out his existing role as the Technical Officer, he took on the role of acting OC 625VGS, leading the squadron through a very difficult 2 year period. He recruited new members of staff and encouraging and training them to work through the flying grades to become instructors. As a direct result of that ongoing effort, 625 VGS was once again able to fly good numbers of cadets at GIC level, and to train a number of cadets on gliding scholarship courses.
Upon the amalgamation of 625 VGS with 621 VGS in August 2013, Flt Lt Rigsby took on the new task of Deputy OC 621 VGS Hullavington.
In January 2014 he was recommended for a Commandant Air Cadets Commendation. It was awarded at a squadron Dining In Night to celebrate the 75th Anniversary of the Air Cadets.
