The spirit (or should I say ghost) of Richard Feynmann lives on.
I'm really, really surprised that the sliver wasn't accounted for during the modification. Aircraft maintenance and fabrication is normally much more focused on accounting for everything that goes in and out of an aircraft. Lost fasteners must be found and so forth.
This is indeed "frightening." Maybe Design News should be highlighting this kind of scary story as we approach Halloween.
What stands out to me is how the crew's attitude changed when Len hit the "gear up" switch. He was right from the beginning, but no one took his concerns seriously until he had a physical demonstration. Then he quickly won everyone to his side.
This should be a lesson to all engineers that "show" is better than "tell."
That's why it's so important to do a complete and thorough preflight, especially after any service. Thankfully I've never found any problem other than compass deviation. From time to time I've mentioned that people should do predrive with automobiles as well. At the very least, check all your tires every time you get in the car, and stomp on the brakes to see if they work.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
