On the human factors side, the MH 370 flight deck crew is portrayed in a Wall Street Journal article as having that low profile that so many of us in the business crave:
Extensive interviews with friends, colleagues and family offer a more complete picture of the two pilots. What stands out most about Captain Zaharie Ahmad Shah and First Officer Fariq Abdul Hamid is just how ordinary their lives appeared until Flight 370 took off.
To many colleagues and classmates who knew Mr. Zaharie, he was noteworthy precisely because he didn't stand out.
"The guys who are too smart get the airplane into trouble. That's also the case for those who are dumb," said Nik Huzlan, a former Boeing 777 pilot and colleague of 30 years at the airline. Mr. Zaharie "wasn't bad and he wasn't outstanding. That's what you look for in a pilot."
...Mr. Huzlan eventually became chief pilot, a job that involved handling discipline problems. Most pilots, including Mr. Zaharie, were never a cause for concern, he said. "Zaharie is the ideal pilot, an invisible pilot," he said.
