Do you not have anything better to do than criticise every detail of everyone elses posts (and PM them into the bargain, just to make sure they get the point - HEATHROW DIRECTOR)
Did I claim to have seen it myself - please read it again. Do I claim to be an expert in any form of aviation - er, no because I'm not.
The incident in question occured at an airshow ( I BELIEVE sometime in the early to mid 70's just after I was born, sadly I didn't make a note of the details) when the aircraft in question was not due to appear but in fact diverted from other business to give people a bit of a show.
It had APPARENTLY come from some distance at one hell of a rate of knots en-route and passed over the airfield, thus the 'approach' I refer to was not an approach to the airfield but an approach to the show, before exiting very soon after (very convenient, yes, but also true). I ommited absolute specifics as it was purely an illustration of some of the stranger aspects of aviation and the potential for 'mythology' therein, NOT a claim to have witnessed the event.
