Hi, Remi
The loss records as I have them are:
http://www.ahs.no/ref_db/lw_loss_pub...?lossid=127281
http://www.ahs.no/ref_db/lw_loss_pub...?lossid=127515
So at least you have 8 crew members here.
As I stated earlier - if this Beckmann was killed in connection to this operation a Namentliche Verlustemeldung should exist. A further possibility is of course that he was for example a reporter flying in one of the crews, and that he thus is reported under another unit.
A further complication, especially when trying to find a suitable loss is that the name Beckmann reported from memory could have been written or reported in numerous ways - you have Beckmann, Bachmann, Backermann, Backmann, Bahlmann, Bahmann, Ballmann, Beckermann and so on...
I can find no loss with a suitable name for this date, but haven't entered the losses for Schulen and sonstige units yet
Regards,
Andreas B
