This event happened when I was a young boy, just pre-teen when I'd guess I was about 12.
I'm now 65 and want to post this report before I can't.
This would put the event in the very early 1950s.
I lived in Calumet Park, on a small farm, about 20 miles southsouthwest of downtown.
One afternoon I was standing in the yard looking due North.
Coming out of the West there was a very high, extremely fast round object moving West to East.
The speed was unlike anything I had ever seen.
Many times that of the fastest plane.
From the ground the view angle was probably about 60°.
From my distance it appeared to be about 3 or so times the size of a pin head held at arm's length.
When it was due North of my location it came to a stop, motionless.
It remained that way for several minutes.
Then another identical object came from the East at the same blazing speed.
It came to a stop right by the other one.
Now there were 2 of the round objects together.
They hovered for a few minutes.
Then they went straight up, got smaller and smaller until I couldn't see them any more.
There was no sound, no vapor or contrails.
The day was bright and clear, not a cloud in the sky.
Just a perfect summer day.
I remember the temperature being plesant too, which would normally mean early summer or late, late spring.
In the above part of the form I'm only guessing month/day/year.
