Andreas
I am puzzled about one loss listed by you and that is WNr 500642
http://www.ahs.no/ref_db/lw_loss_pub...?lossid=103175
Checking various second hand sources of mine, according to
a) The Messerschmitt 262 combat diary, it was WNr 110615 9K+NL in which Rudolf Hoffmann was killed
b) Me 262 Vol 3 (Classic 5) says it was WNr 110615 piloted by Richard Hoffmann
c) Me 262 the production log says that WNr 110615 9K+NL was lost already on 2 Feb 1944 (going back to Me 262 combat diary, well it is there too....

)
d) Looking at the web site
http://www.stormbirds.com/werknummer/block3.htm
WNr 110615 is listed as lost with the double dates under question marks.
"Your" Wnr 500642 is not listed in any of the sources above, so is it possible for you to expand and verify that this really is the correct WNr for the loss in question? It certainly fits better than the present thesis that 110615 rose from the ashes and was again lost 12 days later. It also seems more realistic with the code 9K+CL. Finally I also notice your slightly different spelling of Hofmann. Also can we unite that his first name was Rudolf?
Cheers
