While a student on 242 OCU at Thorney Island I witnessed this aircaft crashing. It was doing a training sortee with a OCU captain. After a simulated 3 engine approach the "idled" engine did not respond when power was applied for the usual "touch and go", and veered off the runway, sadly fatally injuring a Sgt in the ground radio hut. I think the trainee captain was Flt Lt Brown? and the training captain Flt Lt Ireland? Although a latecomer to the Hastings fleet, I well rember a situation on take-off from Benson during a stream take-off when we were caught in a slipstream and it was the skill of Flt Lt Roger Jones that saved the day for us all then
