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 cant 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 Dont let him drive crazy thx
