So, how is a DC9 a long RJ?
DC-9/MD Super 80 series is 132 inch OD diameter tube
CRJ/Challenger jet is 106 inches.
26 extra inches... about enough for one more row of seats in the Douglas product, which of course, it uses. It's "taller", 'cuz the tube diameter is that extra 26 inches.
I have to say that the CRJ "Next Gen" aircraft have come a long way to make it feel roomier compared to the first gen CRJ-100. That's do, at least in part, to lowering the floor and raising the windows (windows are bigger, too).
