In 1994 from the front window of a PA28 cruising at around 3000’ over County Durham I saw the form of a man appear from the distant haze, silhouetted by the low winter sun. The sight was reminiscent of Da Vinci’s Vitruvian Man, the old “World in Action” man with arms and legs outstretched. It grew in the windshield and just as I started to think I was seeing a divine vision it flashed past the aircraft about 100 yards to the left, maybe 100’ feet below and I realised what it was - an inflatable Michelin Man that must have broken free from it’s tether on some garage forecourt.
