If you will be flying anywhere in the United States over the next few months, prepare for a few extra minutes in the security line.

Al Qaeda published a new “online recipe” for creating bombs that cannot be detected by the current security measures in place at airports.  The result is that the TSA will be conducting random spot checks of carry on baggage at all airports.

Jeh Johnson, head of Homeland Security, met with airline officials to provide them the details of the terrorist thread.  The guidelines from Al Qaeda not only included the bomb mixture but also told bombers where to sit on the planes for maximum damage.

“We have no specific, credible intelligence of an attack of the kind in Paris last week being planned by terrorist organizations in this country,” Johnson said in a statement. “But, the reasons for these measures should be self-evident to the public: the recent attacks in Paris, Ottawa, Sydney, and elsewhere, along with the recent public calls by terrorist organizations for attacks on Western objectives, including aircraft, military personnel, and government installations and civilian personnel.”

“The chief Al-Qaeda bombmaker Ibrahim Al-Asiri is innovative in his designs and isn’t to be underestimated,” security expert Ryan Mauro told FoxNews.com. “For Al Qaeda, it is still somewhat of a victory if they can get an explosive on an airliner or even just inside an airport, regardless of whether the device ignites properly.
