Well if Bomberdier won't do it, then a third party conversion should be started. In addition to the Qs, they could stretch 50 seat CRJs into CRJ 700s and 900s and could also stretch ERJs into 70 seaters easily. This would allow cash strapped smaller regionals an economical way to get into larger RJs without the large capitol outlay of buying new.
Wow.
