[Franek Grabowski]

So it looks that Tim is just too modest with his approach to own memory!
Tim, personally, I would rather believe that you somehow learned the time, be it a glance on a clock, a word from the people down on the ground, who helped you, or perhaps a document that you have seen back on the Squadron. Please note, that Wick (if it was Wick of course) claimed his victory at 1335, so there is still some inaccuracy. The base patrol - I can imagine you forget about it, it was a daily routine, nothing to bother with.
I am very glad of this discussion as it developed.
We have some documents, we have a witness, but we still have problems to establish what actually had happened. A nail to the coffin to those who believe such tie ups are easy.
