Airplanes take advantage of four forces. Lee Dempsey/HowStuffWorks.com Drop a stone into the ocean and it will sink into the deep. Chuck a stone off the side of a mountain and it will plummet as well. Sure, steel ships can float and even very heavy airplanes can fly, but to achieve...
Drop a stone into the ocean and it will sink into the deep. Chuck a stone off the side of a mountain and it will plummet as well. Sure, steel ships can float and even very heavy airplanes can fly, but to achieve flight, you have to exploit the four basic aerodynamic forces: lift, ...

Climate change is affecting air travel in a few ways: extreme heat can make it harder for airplanes to take off, flooding from storm surges and sea level rise is a greater risk for airports and the risk of mid-air lightning hitting planes has increased. ...
If you have ever had dreams of being a pilot, the paper airplanes and paper airplane activities for kids in this article are for you and your kids. Many of these paper airplanes are based on actual airplanes, like the Thunderhawk or the Thunderdart. Other projects include aviation marvels ...

During peak air travel times in the United States, there are about 5,000 airplanes in the sky every hour. This translates to approximately 50,000 aircraft operating in our skies each day. How do these aircraft keep from colliding with each other? How does air traffic move into and out...
The tricky part in the construction phase was making them sturdy enough to withstand deep-sea water pressure, while being light enough for transport by airplanes, ships or trucks. The first two DSRVs were in the water by 1970 for testing. After successful rescue exercises were completed, the ...
Sometimes, they say, international pilots instigate a go-around when they see other airplanes too close for comfort at a US airport, surprising local air traffic control. “They’ll say, ‘Why are you going around? You can see it!’” they say. “I’ll guarantee you that there’ll have...
