I've been sitting on this for 26 years because it sounds absolutely mental, but I need to tell someone who won't immediately think I've lost the plot. This happened when I was driving back from Plymouth to London after a late shift at a logistics company.
Around 3:47 AM (I remember checking the clock), somewhere between Bodmin and Launceston, my car just... died. Engine cut out, lights off, radio static. I coasted onto the hard shoulder and stepped out. The whole road was completely silent - no crickets, no wind, nothing. The sky had this sort of greenish tint to it, which is mental because it was a clear night with stars.
I saw something hovering about 200 metres away in a field, roughly triangular but with a strange shimmer effect. I watched it for what felt like ten minutes but my watch showed only 90 seconds had passed. Then it shot upwards and my car started again immediately. The clock showed 4:12 AM.
I've never told anyone in real life because I work in engineering and I'd be absolutely rubbished at work. But I've seen the Bodmin Moor sightings referenced here before, and I wonder if this was part of the same flap?
