I remember Echo I.  My dad and I would stand on the front steps, and
watch it going over with his old WWII binoculars that he found in a
bombed out bldg in Germany during the war.  I remember it being very
bright.  I must have been about 8 yrs old then.  Wish he was here yet to
stand outside with me.  He liked this stuff.
