The plane so good it's still in production after 60 years. http://www.bbc.com/future/story/20170302-the-plane-so-good-its-still-in-production-after-60-years I learned some good new stuff in the article :
Wow. I saw something similar yesterday about why big commercial jets fly more slowly today than they did in the 60s. They compared the three major types of aircraft engines, turboprop, turbofan, turbojet. They then showed examples of 'prop' planes. "Almost any propeller plane you see today is a turboprop." Meanwhile all examples are pistons. Then he talked about high bypass turbofans and completely got the explanation incorrect. Then, he want on to talk about how aircraft do not cruise above .8 mach or 750 miles per hour (apparently that's the speed of sound?)... You know what, screw it, here's the video...
