Fred Morrison’s wonderful invention, the Frisbee

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/02/Frisbee.mp3[/podcast] Fred Morrison died on Tuesday at the age of 90, one of those people you may never have heard of, but really should have. Morrison invented the Frisbee. Since millions of these and other flying discs have been sold since the 1950s, it’s perhaps a bit humbling to discover, though, that even though throwing a Frisbee well is a skill that can be acquired, nobody has pinned down all the details of the science involved. Morrison, born in Richfield, Utah, said the inspiration for the Frisbee went back to a Thanksgiving Day picnic in 1937 when he and his girlfriend (and future wife), Lu Nay, began throwing the lid of a popcorn tin back and forth. They soon found that a tin cake pan ...

Tired of computer flight sims?

Now you can build your own Spitfire...from a kit.The importer of the packs, Kieran Padden, says that business is booming - and for many reasons. "It is so easy to fly," he claims of the plane that costs a tenth of the original to buy. "Even old Spitfire pilots I have spoken to say it flies just like the original. It's lighter but has the same performance, so it's much more agile."The V6 engine means that the completed plane will travel at 222 mph and can fly up to 18,000 feet. "The manufacturers have even recreated the sound," says Mr Padden. "Every time I hear it, the hairs on the back of my neck stand ...

Test flying a 70-year-old airplane

A pilot (with a great sense of humour) gets his first chance to fly a DC3, more than 70 years after the famous aircraft first took to the skies. Today, decades later, scores are still in operation.My favorite line:I was much taken by the crew escape hatch on the left-hand fuselage side, just behind the cockpit bulkhead, because if, during an evacuation, the still-turning left propeller (the tips just missing the hatch by inches) didn't kill you, the 25ft (7.6m) drop certainly would.Well worth a read if you have an interest in old airplanes, or airplanes in general.(Via DefenseTech.)

Hypersonic flight

Less than a hundred years ago, the Wright Brothers made the first powered airplane flight. Next month, NASA will fly a whole new type of airplane, faster than anything that has flown to date: not just supersonic (faster than the speed of sound) but hypersonic (MUCH faster than the speed of sound). Of course, NASA has a number of advantages over the Wright Brothers, not least the fact that nobody has to actually sit in the X-43A to test it--a good thing, it's going to crash into the Pacific Ocean at the end of its flight. The current speed record for flight, Mach 6.7 (6.7 times the speed of sound, or 7,230 kilometres per hour) was ...

Kites

When Bob Dylan wrote about answers blowin' in the wind, he must have had Saskatchewan in mind: here on the prairies, just about everything is blowin' in the wind. (Whether that includes answers depends on how well the kids up the street held on to their homework, I suppose.) You can't change this fact of prairie life, but you can choose how to deal with it: swear at it, or go fly a kite. For more than 2,000 years, people have chosen to do the latter. They probably started in China, which has the longest recorded history of kite-flying and even had a holiday called Kite Day. Other Asian countries also have strong ...

Skydiving

  "Go!" yelled the instructor. Over strenuous objections from brain and body, I let go of the airplane's strut and stepped sideways into 3,500 feet of air. I fell: two simple words that don't do the experience justice. I'd been training all day. I was supposed to arch and count to five. I didn't. Every thought dissolved in a sensation far greater than fear. Gripped by forces beyond my control, I flipped and twirled like a leaf in a hurricane. Then suddenly I felt a solid tug, and floating instead of falling, I looked up at the most wonderful thing I'd ever seen: my parachute, glowing serenely blue in the sunshine. # Parachutes have been around a long time. A Chinese history from ...

Flight

In this age of 747s and Concordes and supersonic jet fighters, it's sometimes hard to realize that airplanes have existed for less than a century. Even manned gliders, which came before powered airplanes, have only been around for slightly over a hundred years. In fact, 1991 was the 100th anniversary of the first glider flight by aviation pioneer Otto Lilienthal. Lilienthal believed that the best way for humans to figure out how to fly heavier-than-air craft was to first figure out how birds fly--after all, birds are heavier than air, too. He began systematic aerodynamic studies of bird flight, and in 1889 published his results in a book, Bird Flight ...
