Laying on my back looking at the stars when one shot across the sky, did a 90° turn without slowing and stopped, then a second one did the same maneuver.Got witnesses outside and this was repeated 4 or 5 times.
These lights, of course, were not stars.
The lights were very, very high in the sky on a night that the stars were all out.
They made a pattern like a Tic-Tac-Toe pattern.
The 90° turns without slowing is what was really impressive.
I'll never forget it, but have not told the story all this time for fear of ridicule.
