Summary: "Unfortunately, sometime around WWII, Newton’s laws were replaced by the Bernoulli theorem and a hand-waving argument for the acceleration of air over the top of a wing. It is our hope that teachers will return to the basics and use Newton’s laws to describe lift. Then students can explore flight in much more depth than was possible with the popular explanation using Bernoulli."
The wings of an airplane in level flight direct air downward with a force equal to the airplane's weight. If one were to build a large scale on the ground, as an airplane flies over it, the scale would register the weight of the airplane.
The wings act like a scoop forcing air downward behind the wing. At least that's the way I think about it when I'm out flying around in my Cessna.
A Cessna Caravan airplane does not land itself. It's a thoroughly manual process. As a pilot, I'm in awe of the controller and passenger for being able to pull this off.
Pilot here. I'm floored that a person with no flying experience could put this airplane down without a scratch.
Air traffic controllers are not necessarily pilots, but luckily, this one was a pilot and certified instructor. ATC and passenger worked through a stressful situation to produce an amazing outcome. Bravo!
Dr. Allison recently was awarded the Nobel Prize in Medicine for his persistent decades-long pursuit of using our own immune system to combat cancer. I was diagnosed with Stage 4 melanoma in early 2017, and I have been cancer-free for almost five years. Thank you, Jim.
