Hi Ian,
Thanks for your kind answer Ian.
Effectively this is not clear: In two references you gave (Prien and BoB...) there is something which isn't clear: One is talking about a "Belly landing" the other one of a "Crash".
I must admit that the fact nothing is mentionned in his Soldbuch concerning these wounds did help me - if not push me - to point you these two pictures.
Last, it's important to say that after a mission flight, after a possible air combat, pilots do come back "much older", for a while at least; Mombeeck books are full of this kind of comments. Another reason which push me in this direction...
Better try than doing nothing
.
Best regards, Franck.
PS: I did change my avatar picture; the new one is a 4.60Mb, 4200x3300 and is spectacular. If someone is interested to get it just let me know.
