Actually the document came from the airforce historical research center. As some of you have said this document is not accurate. To be honest Im not surprised in the least. Any documents including those of other goverments always have some thing wrong especially when it for claims or losses. I use documents like this as more of a starting point. Its amazing how much data is wrong especially when an aircraft is recovered. Many aircraft thought to one thing have turned out to be another.
Any way good luck in any type of research any one is doing.
Discounting the whole document is like throwing the baby out with the bath water. We all know that the Victory Review boards cleaned up lots of this stuff. Hell pilots have had records re-assessed as little as 5 years ago.
