All the six engined Bv222 flying boats were accounted for after WW2, albeit one was not located until recently, scuttled by the british in Norwegian waters after the cease of hostilities. The aircraft described could only be a Junkers Ju-390 opening a whole new can of worms with conventional historians who insist only one Ju-390 flew even though Junkers were paid on 29 June 1944 for seven completed Ju-390 airframes.

This discovery opens the question of whether there was an attempted attack on USA in 1944 with WMD?
