I read a thing the other day about the fundamental difference between flying a plane and flying a helicopter is that airplanes are dynamically stable but helicopters are dynamically unstable.

If you are flying a plane you can let go of the controls for a long time and it'll just fly along on its own. You can lose all your engine power and just glide for like 100 miles until you can find a place to land.

A helicopter, on the other hand, is like balancing on top of a column of air. You cannot let go of control at all. If you need to reach something in the cockpit, you have to shift hands and keep grip on the controls. You are constantly making minute adjustments with your hands to keep the blades balanced and your air column directly underneath you. A few seconds' loss of control and you will tip to the point that it's unrecoverable.

Something something maintaining constant, tight control Tommy Kinard's personality something something.

The Federal Aviation Administration receives thousands of complaints every year about the characteristic loud buzzing produced as drone propellers slice through the air. That noise is an issue in other countries, too: Canada and England, for instance, report a sharp uptick in similar complaints over the last several years. Experts believe noise pollution caused by these unmanned aerial vehicles will only worsen as they are increasingly used for package delivery, photography, emergency response, and more.

Paris 2024: Bouncing and Spinning

Spin, or the lack thereof, plays a major role in many sports -- including tennis, golf, football, baseball, volleyball, and table tennis -- because it affects whether flow stays attached around a ball, as well as how much lift or side force a ball gets. A ball's spin doesn't stay constant, however.  (Image credit: J. Calabrese; research credit: T. Allen et al.) Find all of our Olympics coverage -- past and ongoing -- here and every sports post here.
