This is no laughing matter.
Saw a Mitsi Solitaire come in to MEM last night out of West Memphis using a "Midsouth" callsign. What's strange is that there's only a -36 L model listed on the certificate (that I can find, anyway). Are they expanding the fleet? More to the point, do they need a mitsi driver? Contact info? Anyone? Bueller?
They have or used to have a Shorts 330 painted camo. Also have or used to have a few metroliners.
