The vernal equinox came and went quietly yesterday on a clear, blue Sunday in mid-Michigan.

On March 20, 1966, dozens of people claimed to have spotted a UFO hovering around Dexter, MI, near Ann Arbor.
The next day, a similar report came out of Hillsdale.
The rash of sightings made national news, and even caught the attention of veteran newsman Walter Cronkite.
But what was the thing all those people saw?
