About me? Well I'm enjoying my third career now and haven't even died of old age yet! Being a famous writer was an interesting goal decades ago but I developed a terrible addiction to eating food and living in a warm building so I ended up working for a living
+ more bio informationHow can a machine be light enough to fly but strong enough to stay intact under great stress? How can a wing carry fuel and engines without breaking off? All while being made of beer can aluminum? One key is the material aircraft are made of. Aluminum is almost always alloyed with other metals, often copper or magnesium, for... More..
Ask someone you know if they are prepared for an emergency on the road in their vehicle. Most will say "Oh yes, of course, only a fool wouldn't be!" Then go out to your car and pretend something has gone very wrong. Just what kind of emergency ARE you prepared for? Consider a couple very real possibilities: You just stopped ... More..
We all know the Wright brothers built the first successful airplane. But their advances in propeller design are less known. They realized a propeller is really just a rotating airfoil (wing). By applying knowledge gained from their wind tunnel testing on wings, they greatly improved propeller design. Incredibly, their first ... More..
Several years ago I complimented my pilots on their textbook perfect landing at LAX. They politely informed me that the computerized flight control system landed the plane quite automatically. The Wright brothers would have no clue what to do in such a cockpit. But they would recognize what the computers are controlling. The... More..
Our disks act as shock absorbers to separate our vertebrae. They perform exceptionally well but are somewhat prone to damage. A herniated disk begins with a crack or tear on it's outer shell. The inner gel material, which cushions the vertebrae, can then bulge out of the disk. When this gel presses against a spinal nerve roo... More..
If you've tried to hire a drywall installer lately you'll have noticed two things. They are too busy to even answer the telephone, and are expensive. Unfortunately, many people will have to wait their turn and pay what it costs. Why not just do it yourself? If you are motivated and reasonably fit (or have kids or friends who... More..
The majority of procedures and rules in aviation are written in blood. We design and build the safest aircraft possible, given the best available knowledge and skill. Inevitably, an unforeseen circumstance will cause a catastrophic wing failure. Every failure and accident must be learned from to prevent a repeated incident. ... More..
Consider a jet and a propeller driven airplane side by side on the tarmac. The engines will of course look very different. The jets wings will be swept back much farther and it will look sleeker and faster. But most key differences will not be apparent. Airplanes driven by propellers are ideal for applications where efficien... More..
