Birds, insects, animals and fish have been flying for millions of years, while mankind’s ability to fly is a very recent phenomenon.
This fully illustrated ebook explains the physics behind flight (thrust, drag, lift, weight) and looks at various types of ‘flying machines’ including gliders, balloons and parachutes.
The book is based around a series of lectures given by Group Captain Philip Langrill OBE to the Gwynedd Engineering Society.
During his career in the RAF, Mr Langrill experienced at first hand the developments in aerodynamics which saw a transition from piston powered light aircraft to jet propelled fighter planes.

After Phil Langrill learnt to fly, most planes were jet fighters. He was promoted to instructor training large numbers of new pilots, required in ever increasing numbers. For the next 50 years there were large numbers of newer and faster jets. The old piston engine pilots had to be very careful not to run out of aviation fuel (paraffin), as the new jets soon ran out of fuel: speed-distance-fuel-ratio, forcing to baling out, using ejector seats or worse. RAF Guard-dogs were well trained and disciplined, almost all the time.
Formation flying like the Red Arrows at special events, flying Bombers and Jet Fighters requires a lot of training. This prepares every pilot for the plane to be refuelled for long distance flying. Or like flying a car without brakes, to peals of laughter. RAF Guard-dogs were well trained and disciplined, almost all the time. Introduction pages are before the movie (they are a good teaching aid, and nicely help explain the “RAF Ups and Downs” Lecture.
