Stefan, be aware that Bill Bzuk has made a retirement  cottage industry out of ' coffee table aircraft buff conspiracy books' to quote Melvin Conant. His seriously flawed article on the Avro Arrow can't be improved , as as he rolls back any documented research that disagrees with his "buff books". Avro Arrow is the ONLY aircraft article on Wiki with "political", "Black Friday", "airplane models," & other assorted 'junk.'

Ignore him if you can. Reasoning with him is pointless. Don't let him drive crazy.
thx
