Additional notes....

On the -10 there is no lav in the front. Pilots enjoy the -10 because it has a great thrust/weight ratio....read: sports car. The -10 flies into several cities. Have flown it into Lansing, Omaha, Harrisburg.

The -40s are underpowered. Heavier, but without the larger engines. Carries 10 more people than the -30.

The best way to ID the -50 are the chin strakes under the cockpit. These act as little wings and help the aerodynamics of the longer fuselage.....i.e. help keep the nose up.
