1. An aircraft comprising:
- a fuselage having a longitudinal axis;
a left wing extending from said fuselage;
a right wing extending from said fuselage;
a tail section extending from a rear portion of said fuselage;
a first engine disposed in said fuselage;
a second engine disposed in said fuselage;
said first and second engines being operably connected to a first common driveshaft traversing through said first and second engines and having an axis of rotation oriented transverse to said longitudinal axis of said fuselage;
a first propeller rotatably mounted to said left wing and operably connected to said first common driveshaft; and
a second propeller rotatably mounted to said right wing and operably connected to said first common driveshaft;
wherein said first and second engines are configured for freewheeling such that if one of said first and second engines loses power the other of said first and second engines continues to power said first and second propellers.
