I understand the Germans were ordered to desynchronise their engines when approaching UK because they knew of our efforts to use sound location, one of the concrete mirrors can still be seen on top of the inland cliff overlooking Romney Marsh.
But threepointers were the mark of a polished pilot, my man loved to show off his Mosquito landings! but ran the risk of the dreaded swing.
Going well off the point, your bit about a bit of power on the approach, reminded me of an incident at Wattisham in the middle '50's. The proper fighter pilot break and landing is to approach the runway at high speed, close the throttle and zoom turn onto the downwind leg, lower u'cart and flaps , turn finals and land, all without again touching the throttle.
A Wattisham Hunter pilot attempted this one day and discovered late on the approach that he did need that little extra bit of urge. When he went for it the engine had flamed out and he touched down in the undershoot. When he reached the end of the runway the undercarriage was wiped off and he finished up sliding sideways along the ORP (a concrete layby where fighters were marshalled to scramble on exercises).
At the end of that stood the runway controllers caravan, the occupant of which had watched the whole exercise. He decided to bale out but was too late and found the Hunters wingtip stopping a few feet away from the steps out of the caravan.
