He Don't Know History

From Fox News: Someone deliberately diverted Malaysia Airlines Flight 370 and shut down communications with the ground, and the jetliner continued flying for six hours, Malaysia's prime minister said Saturday. The announcement shifted the focus of the investigation to the crew and passengers on the plane, which has now been missing for more than a week.
Prime Minister Najib Razak's statement also meant the flight path of Malaysia Airlines Flight 370 to Beijing could have strayed as far as the southern Indian Ocean or northwest to Kazakhstan, complicating the work of search crews who already have been scouring vast stretches of ocean seeking the plane's 12-person crew and 227 passengers....
Mike Glynn, a committee member of the Australian and International Pilots Association, said he considers pilot suicide to be the most likely explanation for the disappearance, as was suspected in a SilkAir crash during a flight from Singapore to Jakarta in 1997 and an EgyptAir flight from Los Angeles to Cairo in 1999.  
"A pilot rather than a hijacker is more likely to be able to switch off the communications equipment," Glynn said. "The last thing that I, as a pilot, want is suspicion to fall on the crew, but it's happened twice before."  http://www.foxnews.com/world/2014/03/15/malaysia-airlines-search-heads-toward-indian-ocean/
Umm, but the 9/11 hijackers turned off the transponders in 3 of the 4 jets of the jets they hijacked. So, it is possible hijackers turned off the transponders.
And apparently, other electronics were also turned off in the plane, an indication that more than 1 person is involved in the hijacking.
And if the pilot was solely responsible, how come no communication was made by other crew members, like flight attendants, and people using their cell phones to say what was going on?
Hopefully, Glynn is not helping in the investigation.
