Certificate of Commendation, 1940: "On the 7th October, 1940, FLt-Capt Henderson made a successful landing without damage in a Wellington aircraft in spite of the fact that the elevator control had broken off causing him partially to lose control, and that at the time the wind was strong and gusty"
From 1941 until Dec-42, Chief Test Pilot in ATA's Technical Department, responsible for producing many of the early 'Pilots Handling Notes'.
Certificate of Commendation, 1943: "On the 10th April, 1943, Flt-Capt Henderson was instructing on a Halifax aircraft. During the course of approach the up lock control handle of the undercarriage port leg broke off leaving the leg locked up. Flt-Capt Henderson thereafter displayed great initiative and ingenuity. With the only tool available - a crash axe - he chopped away the back of the rest bunk and made a hole through the fuselage wall, thereby laying bare the broken pull rod. The broken piece of the rod was then unscrewed from the tee handle by nipping it in the hinge of the armour-plate door. He then screwed the handle back on to the remaining threads of the pull rod and was enabled thereby to lower the undercarrige by the normal manually operated emergency system. The aircraft was then landed without damage, thereby saving a valuable aircraft and preventing possible injury to his crew."
He celebrated his fifty-first birthday (15 Jan 1945) by beginning the task of delivering a Spitfire from Hawkinge in Kent to the French Air Force Wing at Luxeil. "When the pilots arrived to collect them [12 Spitfires] the landscape was covered in snow, the temperature was well below zero and a biting east wind blew in heavy gusts." BG
