Hi Simon,
Im relieved that you are still with us and able to report this incident on the forum, to quote your words: "I had a close call from a light Aircraft. When I say close I mean 20 meters in front of me, banked fully over to the right in the air 20 meters at the converging speeds that we were both at was VERY VERY VERY close. The pilot must have been alseep."
It could have been a different subject heading, other than 'Near Miss'.
Obviously this incident compromised Rob's, Colin's and your safety.
Is it subject to an Airprox report? (Maybe Norman could advise)
If so, the Pilot of the light aircraft will be informed, if not already aware of this near miss.
See Ya Soon
Terry
