Honestly, the whole security thing has gotten so completely out of hand that I hesitate to even write this, but since it’s come up:
The Association of Flight Attendants has asked the government to ban in-flight wi-fi because they believe it poses a security risk, and the pilots’ union ALPA has also said that they are concerned with passengers having Internet access in-flight.
The belief is that a terrorist could trigger a bomb using in-flight wi-fi in lieu of triggering a bomb with a cellphone, which is (of course) banned in-flight (except on planes where it’s not banned in-flight).
Smart intelligence (as we saw with the most recent Yemeni printer cartridge caper) is the only way to stop terrorists from doing horrible things to airplanes. They have exploited every loophole in security, and they will continue to do so. Essentially shutting down the commercial air system is the only way to keep it 100% safe (on a barely related note, people talking on cellphones are responsible for thousands and thousands of traffic-related deaths each year, and yet people continue to fight those bans or flaunt the rules; flying is incredibly safe, and would be incredibly safe even if we allowed 4.5 ounces of toothpaste on board).
I’ve stopped assuming I can guess what the government will do when it comes to airplane security, but just know that you will be no safer if they take away your wi-fi.
