Hi ATC Watcher, sorry for the slow reply, but I have been busy recently. You said.. ''As to PPL instructons well the crew here were no PPLs,''
This is not true.. All pilots either military or commercial start off with the PPL syllabus, and one of the first recommendations is to limit the AoB whilst in the circuit.
As for the position of the crash, I have only been able to find one reference to this, and it puts the location just a few yards short of the centre-line.
