Alan,
I was a Floater. I remember Crewing 63-7771, 63-7773 and 63-7775. There were others. I would return to CCK on one plane and step on another and go back to TSN. Starting in March 1971 I went 126 days with only 4 days back in CCK. When Capt. Young, our Maintainance Officer found out, he made sure I got a break. 63-7773 is now on permanent display at Fort Indiantown Gap in Pennsylvania.
We most likely did cross paths
