Johnson said the enhancements, also adopted by European aviation authorities, “are designed to provide an additional layer of security for the traveling public, and will be undertaken in consultation with relevant foreign governments and relevant passenger and cargo airlines.”
They include expanded screening and other “seen and unseen” security measures.
A DHS official, who asked not to be identified because he’s not authorized to expand on the secretary’s statement, said the new measures would be phased in as quickly as possible.
“This is all within TSA’s capabilities, within their power, within their authorities and resources,” the official said. “If we say ‘From now on a certain item poses a threat, no one’s allowed to bring that item aboard a plane.’ We can request that and if [other countries] refuse to [ban that item], we can refuse planes coming from that airport or from that country.”
He would not specify any category of items or cargo that might be banned from airplanes under the new order.
He said the new expanded screening and restriction of items brought aboard aircraft likely would apply primarily to those stowed in the cargo hold. In most airports worldwide, passengers and their carry-on bags are subject to x-ray machines, metal detectors and, in some cases, bomb-sniffing dogs.
“Obviously we could dial it all the way up and say you can’t bring anything at all in your carry-on, but that’s not workable, and it’s going to make everyone very angry,” the official said.
The official added that the tightened security measures were planned in conjunction with security agencies in Europe and the Middle East.
“It’s not like we’re deploying TSA agents abroad,” the official said. “There are TSA equivalents in every country, and these talks and consultations are always ongoing with them.”
The cause of the crash of the Russian jet, which could be the result of an explosive on board, a catastrophic mechanical failure, human error or an accidental explosion of fuel, remains a mystery.
