Pro move: The trick also works in the window seat on most planes. So if you’re trying to lean against the window for a nap you can lift the armrest and give yourself an extra few inches of space.

John Collins designed the current world-record-holding paper airplane. According to him, there are four things to consider when making a paper airplane: the paper, lift and drag, location, and the ...

Unlike with passenger plane, paper airplanes are not propelled forward by engines but rather by their initial toss. Paper airplanes fly due to four main forces: drag, gravity, thrust and lift.

Planes get 1% less lift with every 5.4 degrees Fahrenheit (3 degrees Celsius) of temperature rise, Williams said. “That’s why extreme heat makes it harder for planes to take off – and in ...

MIT scientists are putting wind beneath policy makers’ wings, suggesting ways to modify airplane emissions, which worsen air quality and contribute to thousands of deaths annually.

The first time I saw one of these was in a clip from Going Deep With David Rees, on the "How to Make a Paper Airplane" episode. In that demo, a skilled practitioner was pushing it along simply ...

How high do planes fly? Commercial planes fly between 35,000ft and 42,000ft these days which is around 6.6 miles up in the air. But if they go too high it wouldn’t be good for anyone on board.

This causes a sudden drop in lift, making it hard for the aircraft to stay in the air. Pilots work hard to avoid stall, and any design feature that delays or reduces stall can make flying much safer.

How To Make the Perfect Paper Airplane Jennifer Leman A graduate of the Science Communication Program at UC Santa Cruz, her work has appeared in The Atlantic, Scientific American, Science News and ...
