Since when has the angle of terrorist attack shifted back to blowing up planes instead of flying them into strategic targets?

A laptop with a fully charged battery can cause a lot more havoc over the Atlantic ocean than one with the drained battery. Presumably you could bring in a couple of extra batteries as well, because it's going to be a long flight.

If they're worried about someone building a bomb into the insides of a laptop that you can't turn on, then hasn't that been pretty much the core of airport security since its inception -- and pretty much a problem solved to all practical extents since several decades ago?

I mean, that's why they've been scanning all cabin baggage for decades to see if there are guns inside radios or tanks of interesting liquids inside some suitable item. They've been looking at the x-rays of laptops for twenty years, and now they suddenly start worrying about bombs being built into one?

And why aren't they worried about the cargo baggage which also contains electronic devices that are potentially uncharged? If they can spot bombs in the electronics in your big baggages without checking if they boot up, then why can't they do that for your cabin bags?

Unlike water bottles that you can dispose, this is going to be a big problem. You just don't leave your laptop or phone at some airport: you simply don't fly.

This makes absolutely no sense whatsoever, and the sickness spreads to airports outside US. This means we soon can't fly with uncharged electronics in Europe either because the same security gates can allow someone to board a flight the USA.

I'm just wondering who is it that benefits from all this? Where does the money go, who are the people who can push these endless rules and regulations for their own gain because there sure as hell isn't a gain for anyone else?

Batteries on laptops and cell phones look like a big opaque block on x-rays[0]. And 6 grams of PETN can do a lot of damage[1].

New intelligence indicates that the AQAP bombmaker responsible for the underwear bomber and the printer bomber has figured out how to replace the battery with a bomb. It's not visible on x-ray, and it's sealed so it won't trigger the explosive trace detection equipment[2] either.

> And why aren't they worried about the cargo baggage which also contains electronic devices that are potentially uncharged?

Presumably these devices would need to be held directly against the fuselage as the underwear bomber failed to do[3], so they'd need to be carried by a passenger instead of in a random location in the baggage compartment.

And it's not about whether the battery is charged, it's about whether the device has power at all. Naturally TSA countermeasures are trivially circumvented. Replace the optical drive with a second battery, it still powers on even if the first battery has been replaced with a bomb.

Some reports say they're looking to surgically implant a device under the skin[4]. How do you screen for that?

Alright, so open up the battery, keep half the cells so the laptop works fine and replace the other half with PETN.
Welcome to the NSA watch-list!

Because you can't swap in a live battery in mid-flight if the device is stuck in the cargo hold, of course. I'm not sure what's so terrible about this, since most people will have a charger with them anyway. If their device happens to be out of battery but they can plug in the charger and demonstrate its safe operation, there's no problem. Indeed, this doesn't strike me as anything particularly new, rather an old story being recycled as churnalism.

The TSA released a statement about it today

http://www.tsa.gov/press/releases/2014/07/06/enhanced-securi...

A statement so vague that it could be construed to mean anything. Every minute adjustment of TSA standard procedures is intended to 'enhance' their security regime.
The secrecy is ridiculous. The bombers and bombmakers already know what's going on. The TSA is just keeping innocent travelers in the dark.
Swapping in a live battery probably isn't a problem. They want to see if the device works or not.

What I meant that if I build a bomb into a laptop, and use its battery space to contain the explosive so that it looks 99.99% the same in the X-ray, I can just put the bomb in the checked in baggage and have it in the cargo space while not having to show anyone that the device doesn't boot up.

But if they can already detect bombs built into devices such as laptops for checked-in baggage — which they obviously(?) and presumably do — then why can't they detect these bombs similarly for cabin baggage? They could just do that instead of asking the passengers to boot their devices.

> They also are concerned that hard-to-detect bombs could be built into shoes, said the officials, who declined to be identified because of the sensitivity of the issue.

Whelp. Better ban shoes too. Otherwise terrorism.

I have an external battery for my X220 which I use on long flights. Just out of curiosity I calculated the equivalent energy in TNT which the batteries hold. It was about 220g. And Li-ion are known for their explosive discharge.
