Your Out There editor can’t find any reason to believe or debunk this story, so here it is:pilots landing an Airbus A320 at Manchester in the UK were surprised to see a man fly past at an altitude of 3,800 feet as they passed over Macclesfield. He wasn’t picked up on radar, and neither pilot saw a canopy above him. If there was no canopy, then he wasn’t in a powered hang-glider or ultralight. There are no mountains nearby from which a wingsuiter could have taken off and reached an altitude of nearly 4,000 feet.
