We often glimpse a plane in the sky with no greater understanding of the principles involved than a caveman. How do these heavy machines take to the air? To answer that question, we have to enter the world of fluid mechanics. Physicists classify both liquids and gases as fluids, based on...
While length, height, wingspan and empty weight are all valid criteria in ranking aircraft, the one aviation industry experts most often use to determine whichplaneis biggest is the maximum takeoff weight (MTOW). That's the most a plane can weigh and still get off the ground; it incorporate...
which may in turn lead to a crash. Even in airplanes that do not crash, turbulence can still cause accidents. Indeed, it is the primary cause of injury
Today's jet airplanes use the same principles of aerodynamics that the Wright brothers used in 1903 to get their Flyer in the air. But how exactly do airplanes fly? Flight requires two things: thrust and lift. Thrust is the forward motion provided by a propeller or jet engine. (A ...
If the disabled submarine is simply trapped or has lost power, the ROV can often cut it free or tow it to the surface. Hard-shelled suits that can withstand pressure as deep as 2,000 feet, known as Atmospheric Diving Suits (ADS), were put into action in 2001. With a constant ...
11 attacks, as well as capricious weather patterns, and you can see why job descriptions for airport managers often contain these kinds of descriptions: "You must have strong leadership and organizational skills, as well as excellent communication and interpersonal skills. This is not a position ...
More often than not, it's not the flying itself you're actually afraid of — that's why it's important to analyze your anxiety before you try to overcome it. "When people come in wanting to address a fear of flying, they will often say that they know flying is a safe form of ...
While a stuntman isn't going out of his way to do something dangerous, creating a realistic stunt often requires high-risk action. Training and technology help make stunts a lot safer than they were in decades past, but if all stunt sequences were perfectly safe, stunt people wouldn't be...
When you’ve found your gate, find a restaurant or cafe to sit and relax. Bring a good book or queue up a (relaxing) podcast to bide your time. Or simply people watch- often, seeing everyone else at the airport doing exactly what you are doing without a care in the world may help...
sport have themselves taken on newer and bigger challenges (such as using wingsuits or airfoils to catch superhuman air at ridiculous speeds), they have expanded the generic meaning of extreme skiing without breaking it, because the evolving hybrid forms still often contain the steep-slope element...
