Never heard of Echo I?

Side story:

They used to publish schedules of "Echo I" visibility on newspapers; I frequently observed it passing overhead in the evening sky.

Yep, hard to believe that was 42 years ago.
I used to watch Echo I though my 50 power refractor telescope
which I had received as a 6th grade graduation gift.

I still have it, and it works great as a 500 - 1000 yard spotter scope.
