You are looking at the crews for lead ships. In the case of 41-28853,
it was flying as the lead ship for the 55th Bomb Wing on 20.11. Lokker was the commanding officer of the 783rd Sq.
There is a history of the 783rd here and you can see how lead crews were made up and sometimes switched around.

Also found this, which suggests that Lokker was actually hung by civilians.
