I was at a public swimming pool with my friend and his cousin.
I was on a 10' diving board ready to run out and dive when I saw a dull silver disk at about 45° approaching from the East travelling at a high rate of speed.
I yelled at my friends behind me on the board to look, keeping my eye on the object and pointing as it went past.
They could not see it.
It was against a broken cloudy sky almost the same color as the disk.
A description of the size of the elliptical object was a little smaller than the size of a dime at arms length.
