I'm just scratching my head here, but what is NOT obvious about the "MU-2 and its class"? Obviously, the MU2 belongs with the King Air, Turbo Commander, Cheyenne, Conquest group of planes--not Meridians, -6,-7,-8 or Beech 1900s.
Factoid--2 in Japanese sound likes "nee", hence MU2 is Moo-ney, the original importer and partner. They should have stuck with the small planes--would have saved a lot of investigators, a lot of time.
