The Mesa Airlines Profile states under fleet numbers that Mesa has one (1) CRJ-200.

Now I realize there is a lot of commonality in CRJ parts and maintenance, but it still seems bizarre to me that any airline would have a single one of anything in their fleet. Granted, it’s only my idle curiosity and no big deal, but can someone tell me if that plane is actually real or not, if it is in revenue service, if it is used as a trainer, if it is used as a company executive jet, or if it’s on a pylon out in front of some company building as a monument - or just what the status is?

Just seems strange is all...
