Jones Beene,
Nobody knows if the Papp engine was real. Papp certainly demonstrated
some remarkable things like a cannon, with many witnesses, that blew up
with more force than a conventional explosive.
Whether Feynman unplugged the wire is secondary to Papp "becoming
agitated" when he wouldn't give it back to Papp. Certainly Papp was
paranoid and eccentric but that doesn't prove anything. what will you
say If Mills manages to demonstrate something real?
I think you have found Papp guilty before (possibly) being proved innocent.
