The noise of flying machines can be a source of joy or annoyance. Let’s have a look at what makes that noise and how much progress has been made over the years!

The language of aviation is treasured by those of us who use it, especially since it separates us from those poor earth bound souls who don’t spend their lives with their eyes cast skyward. In the spirit of fairness, particularly to spouses who stand impatiently, eyes rolling as we converse with our avgeek friends about how pretty that Wedgetail is, here are a few pointers to help you join in the conversation.

I apologise to you all but it’s time for my tatty old RAF log book to come out of the cupboard again. It was a sad, sad situation but for the recently promoted Flight Lieutenant Anderson, his departure from flying the Phantom on 43 Squadron was a reality that he had to face up to. Central Flying School is an august establishment that will proudly inform anyone with an interest (or not) that it is the world’s longest existing flying training school. It was to this anachronistic institution that I was bound!

The subject of UFOs became a very popular theme in the press, on the television and in film, something that Intelligence services quietly encouraged. There were many, very secret projects that the US Government was investing enormous resources in, and any alternative explanation was preferable than the truth. One such project was the Silver Bug, a US Black version of the Canadian Avrocar. However, the Silver Bug’s true capabilities were about to be discovered!  But beware… not everything may be as it seems!

It takes about 12 seconds for the human body to reach terminal velocity.  At that speed they will see the earth’s surface approach them at 177 feet or 54 meters every second.  These are the stories of a few survivors who have fallen from an aircraft, without opening a parachute… and survived!

The landing gear, or undercarriage, of a big airliner is a massive and powerful system. In modern times stowaways, have frequently attempted to hide within the undercarriage wheel-wells of airliners. The chances of surviving such an ordeal are remote in the extreme as the hazards are many. If someone attempting such a dangerous journey isn’t crushed by the movement of the gear as it stows or fall to their death when the undercarriage doors open to raise or lower the gear, then the environment will present an almost insurmountable hazard. Some, however, still survive!

The Hovercraft is something of a rare beast. This story examines the many engineers and scientists who contributed to the development of a vehicle that is lifted on a cushion of air and is capable of travelling over land, water, mud, ice, tarmac, sand and many other flattish surfaces.

The Swedish scientist Emanuel Swedenborg is known to have sketched the first hovercraft design in 1714.

Out of the gloom of thick cloud, through their windscreens, the pilots suddenly saw the tops of pine trees but it was too late to pull up. They ploughed through them as the branches smashed into the left wing shattering the navigation light. One of the passengers onboard was the President of the airline, Captain Eddie Rickenbacker… this is his story.
