The boss would throttle back both engines at say 8,000 feet and enjoy seeing me glide the beast back to the airfield
In view of knowledge gained in later years on the subject of cylinder shock cooling, an extended throttled back glide with radial engines would not have been conducive to good airmanship in terms of engine handling.
Of course that is being wise after the event. At Butterworth in Malaya in the Fifties, the resident RAAF Dakota had an alarming number of engine failures over a three month period. The fault was traced to the squadron QFI who would rapidly close one throttle after take off to simulate an engine failure and leave the throttle at idle instead of zero thrust. He was tasked with conducting recurrent training on squadron crews and this included simulated engine failures by the dozen. It was this abuse of the engines that eventually led to real engine failures.
