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.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
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.
