Hi Greg,
I have scanned my database for information on your uncle and the 2 other men you mention. This database is, by the way, one that supplies the information that you can see on the roster at the groups web site:
http://www.487thbg.org/roster/487thRosterIntro.shtml As to specifics on the names:
1) I do have a Lt. James W. Burt of the 836th squadron. This came from Ivo's book. Perhaps the one letter difference is a misspelling on one side or the other.
2) The only pilot named Robertson that I can find is Captain Hugh B Roberson in the 839th squaderon. He was one of the original crews and I don't know if he was still flying with the group in Feb 1945. Certainly possible, and it's possible your uncle could have been transferred between squadrons.
3) The records do not have your uncle in them. This is possible as he may have transferred in and not been found when various records have been collected over the years, and for instance in Ivo's research of original records. I'm wondering if perhaps he was an experienced Mickey Operator and transferred in from a different group?
4) The mission you mention on 15-Feb-1945 indeed seems to have been to Cottbus Germany, so that checks.
Do you happen to have copies of records of your uncle? I very much want to get him properly into our records and would enjoy the chance to see any 'orders', etc that you have.
You can email them to me at
