(1982) Begins with an example of a helicopter type aircraft from an early science-fiction movie, then covers the evolution of a practical design with old research films made different designs. A female Fokker test pilot recalls her experience getting the first practical helicopter into the air. The leading designers in the US - Sikorsky and Bell - then take much programme time. The aerodynamic principles whereby a helicopter lifts and flies forward are explained Next, the programme looks at experimental technologies of the era in which it was made. An Apple II is used to demonstrate speech recognition used to command changing displays on a CRT designed to replace a multitude of cockpit dials. A one-handed control to simplify two sticks and two pedals is investigated. Helmet-mounted heads-up displays for weapon aiming is demonstrated as designed for the then prototype Apache helicopter.
