Umm, guys to put an end on this, the CRJ into the business jet idea is already taking affect. I have a friend who's company is already buying one and making it into an unreal transcon business bird that is really, really sweet. 20 something seats, aux tanks, new engines and I'm not sure about the autothrottles things, but I'll ask about it. What he said was the company likes it because of the size vs cost. As far as not being able to go up higher then FL410, they get around that by adding huge aux tanks. I'll be you'll start seeing alot, ALOT of birds like this soon, as it just makes sense.
