German airliner crash: A system error with a system solution?

From the Associated Press: Airlines around the world on Thursday began requiring two crew members to always be present in the cockpit, after details emerged that the co-pilot of Germanwings Flight 9525 had apparently locked himself in the cockpit and deliberately crashed the plane into the mountains below.

This represents an organization's typical response to a problem. The crash, which by all accounts was caused by a single deranged individual, has been perceived as the result of a “system error” and will be dealt with as such.

The idea that a flight attendant going into the cockpit whenever one of the pilots has to pee will prevent anything seems a bit absurd to me. How is a 5’2” 120 pound female flight attendant supposed to stop a 6’3” 210 pound pilot who is hell-bent on committing suicide by airplane?

When I tweeted a similar thought yesterday, someone suggested that she could simply sound an alarm and unlock the cockpit door. I suppose that’s true as long as the crazed pilot does not punch her in the face and knock her out or shoot her first.

Question for the 9/11 Conspiracy Theorists

As we approach the 10-year anniversary of the 9/11 terrorist attacks, I am hearing about the conspiracy theories again. Some say that the World Trade Center tower could not have collapsed that way simply due to airliners crashing into them. The conspiracy nuts say that demolition charges must have been placed in the buildings.

There is also talk that the building 7 collapse secondary to the WTC fires "could not have happened" because steel buildings blah, blah, blah. And despite that fact that some Jewish people we're killed in the attacks, there are those who say that Jews were told not to go to work that day because Israel was behind the attacks.

Forget about all the eyewitnesses who saw the planes crash into the towers and the Pentagon.

Here is my question. Over the last 10 years when absolutely no one, I mean no one, can keep a secret for even 30 seconds, how is it that all the guys who set the demolition charges in all the buildings and all the Jews who were called and the people who did the calling have never said one word about what happened?

Not bloody likely.

9/10/2011 ADDENDUM

Last night, @jordjonny tweeted this in reply to me:

"they've probaly [sic] been killed off."

He added a link to a video with the provocative title "911 Witnesses Murdered." The video lists a number of people indirectly or directly linked to the 9/11 attacks who died in "mysterious" and "unexplained" ways. If these deaths were part of a cover-up of the intricate conspiracy, then a number of local, state and federal police agencies as well as the Federal Aviation Administration [there were people who died in plane crashes] would have to be in on it. And all of these public officials would also have not said word one about all this in the last 10 years.

I don't see how that many people could keep such a monumental secret.
