Helicopter Pilots are Different

  “The thing is, helicopters are different from planes.  An airplane by its nature wants to fly, and if not interfered with too strongly by unusual events or by a deliberately incompetent pilot, it will fly.  A helicopter does not want to fly.  It is maintained in the air by a variety of forces and controls working in opposition to each other, and if there is any disturbance in this delicate balance the helicopter stops flying, immediately and disastrously.  There is no such thing as a gliding helicopter. This is why being a helicopter pilot is so different from being an airplane pilot, and why, in general, airplane pilots are open, clear-eyed, bouyant extroverts, and helicopter pilots are brooders, introspective anticipators of trouble.  They know if something bad has not happened, it is about to.”   Harry Reasoner 

UH-1H Iroquois "Huey" Helicopter

With the success of the Bell Model 204 design a need was identified for a larger and more powerful version of this helicopter.  The result was the Model 205 with a lengthened fuselage that accommodated 12 to 14 troops and a larger main rotor blade system.  The Model 205 prototype first flew in 1961 and deliveries as the UH-1D started in August 1963.

     An upgraded 1,400 shp (1044kW) T53-L-13 engine was added to create the UH-!H model, most UH-1D aircraft eventually being converted. The UH-1H is the most common example of the Bell Model 205 helicopter
