Oh, dear, BEagle... it seems your memory has gone rather dotty.
As you well know, but seem to have forgotten, "Dave" is this board's own created nickname for F-35... with "Dave B" corresponding to F-35B.
It is widely used here, and has nothing to do with any simulator, nor with "spotters".
Do see a Doctor about those memory lapses, dear chap... it might be a sign of something serious.
