Hi all,
a friend of mine found an eyewitness report (in German language) regarding this crash:
www.bendorf-geschichte.de/bdf-0159.htm
According to this Link, the a/c (given as B-17 on 8th of May) crashed upon the collapsed Engers bridge. So some of the crew and/or passengers could have been thrown into the Rhine.
Using Google, I found an interesting entry on the 392.BG webside (subject: trolley missions):
"On 7 May, a 389th BG crashed into the Engers Bridge over the Rhine near Cologne, killing 19 men. On 10 May, a B-17 was lost during an air collision over the UK with no known survivors."
Sounds like Engers was really a suburb of Cologne...
Thank you very much for your replies,
A. Heuser
