Manni,
I put the part of the pdf file from AFHRA on the April 11 attack on Aschersleben (139 pages) on a shared Google Drive.
This link should allow you or anyone to look at it (or I believe, download it). The more of us that can look it over the more we may find.

Let me know if you can access it, if not I will try something else.
If the Google Drive works, I will add more things as we go.
I have found the the same crew flew a mission on April 9 in plane 225 X to Naumberg. On that mission they carried 8 x 500 lb bombs. The crew is listed in the same order as the April 11 mission: Hopkins, Lidicker, Wolberg, Samar, Dwyer and Koker. That might mean Koker (listed last both times) was the tail gunner. Just a couple of comments on terms (as I understand them). A "Box" consisted of 3 flights, each flight had six planes. The file includes a map which shows the flight paths of both the main group and Hopkins group which went too far north on the return.
