The late lamented Mike Green taught me a very valuable lesson in clearing turns. Generally pretty good about doing them, except when I was tired after spending an hour as a student instructor, and came to a hover after the last circuit of the sortie.
I spot turned right to head back to the spot a few hundred yards away, only for Mike to gently place his hand in front of the cyclic and point out the Twin Squirrel on very short finals, now in my 2:30 o'clock but which would have been in my 5:30 when I came to the hover. I got a gentle chiding in the debrief and had to make Leon a coffee for that one...
