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.

INTRODUCTION: Birds, Insects and Bats have been flying for millions of years. Mankind for just 100 years, we should thank our great pioneers who showed us how do fly. Each pilot was like a soldier who goes to war with the risk of being killed, or perhaps a racing car drive just wishing to win.
With ever bigger and faster aircraft, a new science was born that of aerodynamics of Thrust, Drag, Lift & Weight. New designs
made possible by computers, and new materials and fuels with a low carbon footprint. We have gone from piloted to automatic navigation to Drones remotely controlled in the last 50 years. From balsa-wood to super laminated light weigh, strong able to withstand high temperatures. Our world was the garden of Eden is becoming over-crowded, we need to change to recycling all waste. A Consuming Society has to re-design all products to be reusable and not to be just discarded.
Our Lecture is by Group Captain Philip Langrill OBE, RAF Ups and Downs, fully illustrated with slides. Part 2
A light-hearted evening for members to learn about the trials and tribulations of a keen trainee glider-pilot. He took to the sport of flying with the result of signing up for a career in the RAF for the next 35 years, ending up being the commanding officer at RAF Valley. Our lecture was fully illustrated with slides describing each autobiographical event in great-detail.
The lecture took on the air and laughter of an after-dinner story with peels of laughter after every joke and revelation.
After Phil Langrill leant 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 re-fueled for long distance flying, like artificial insemination.  Or like flying a car without brakes, to peels’ 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.
