OK, this is a strange one.
Apparently, this day in 1644 has the distinction of being the first UFO sighting in North America by an English colonist. (There may have been other UFO sightings, but I’ll be damned if I can find them.)
You can find the following in John Winthrop, The History of New England, 1630-1639.
In this year one James Everell, a sober, discreet man, and two others, saw a great light in the night at Muddy River. When it stood still, it flamed up, and was about three yards square; when it ran, it was contracted into the figure of a swine : it ran as swift as an arrow towards Charlton, and so up and down about two or three hours. They were come down in their lighter about a mile, and, when it was over, they found themselves carried quite back against the tide to the place they came from. Divers other credible persons saw the same light, after, about the same place.
