Meteor Supersonics...
Asked my father about this. He flew with chap picked up by Bedouin before the incident took place. Stated that he recalled that it was a 208 Sqn pilot although at this stage "mad as hatters" came into the conversation and we moved on.
His answer to the possibility of the Meteor going supersonic was that it could have happened as long as the fuselage and wings were occupying different parts of the sky - otherwise no chance.
