Here is another part of the Avro story I forget about that is also tragic, the Iroquois engine. Also a Canadain desgin, Also highly advanced, also equally awesome:

If anyone is interested, Dan Akroyd did a produced a movie about the Avro Arrow.
I'll warn you, this movie will give you a increibly feeling of pride followed by an incredible feeling of frustration and dissapointment.
