Air Traffic Control "Telephone Glitch" Delays Hundreds of UK Flights

    New on the Internet: a community of people who believe the government is beaming voices into their minds. They may be crazy, but the Pentagon has pursued a weapon that can do just that.

    By Sharon Weinberger
    Sunday, January 14, 2007

    IF HARLAN GIRARD IS CRAZY, HE DOESN'T ACT THE PART. He is standing just where he said he would be, below the Philadelphia train station's World War II memorial -- a soaring statue of a winged angel embracing a fallen combatant, as if lifting him to heaven. Girard is wearing pressed khaki pants, expensive-looking leather loafers and a crisp blue button-down. He looks like a local businessman dressed for a casual Friday -- a local businessman with a wickedly dark sense of humor, which had become apparent when he said to look for him beneath "the angel sodomizing a dead soldier." At 70, he appears robust and healthy -- not the slightest bit disheveled or unusual-looking. He is also carrying a bag.

    Girard's description of himself is matter-of-fact, until he explains what's in the bag: documents he believes prove that the government is attempting to control his mind. He carries that black, weathered bag everywhere he goes. "Every time I go out, I'm prepared to come home and find everything is stolen," he says.

    The bag aside, Girard appears intelligent and coherent. At a table in front of Dunkin' Donuts inside the train station, Girard opens the bag and pulls out a thick stack of documents, carefully labeled and sorted with yellow sticky notes bearing neat block print. The documents are an authentic-looking mix of news stories, articles culled from military journals and even some declassified national security documents that do seem to show that the U.S. government has attempted to develop weapons that send voices into people's heads.

    "It's undeniable that the technology exists," Girard says, "but if you go to the police and say, 'I'm hearing voices,' they're going to lock you up for psychiatric evaluation."

    The thing that's missing from his bag -- the lack of which makes it hard to prove he isn't crazy -- is even a single document that would buttress the implausible notion that the government is currently targeting a large group of American citizens with mind-control technology. The only direct evidence for that, Girard admits, lies with alleged victims such as himself.

    And of those, there are many.

    The proof-of-concept software-or malicious trojans that adopt the same high-frequency communication methods-could prove especially adept in penetrating highly sensitive environments that routinely place an "air gap" between computers and the outside world. Using nothing more than the built-in microphones and speakers of standard computers, the researchers were able to transmit passwords and other small amounts of data from distances of almost 65 feet. The software can transfer data at much greater distances by employing an acoustical mesh network made up of attacker-controlled devices that repeat the audio signals.

    The researchers, from Germany's Fraunhofer Institute for Communication, Information Processing, and Ergonomics[1], recently disclosed their findings in a paper published in the Journal of Communications[2]. It came a few weeks after a security researcher said his computers were infected with a mysterious piece of malware that used high-frequency transmissions to jump air gaps[3]. The new research neither confirms nor disproves Dragos Ruiu's claims of the so-called badBIOS infections, but it does show that high-frequency networking is easily within the grasp of today's malware."

    It's just an unfortunate incident.

    British Telecom has had an issue (which has happened a number of times) which led to a minor timing glitch in one of their systems. When this happens, the data reliability on the FARICE line to Iceland drops and you start getting corrupted flight messages. Shanwick was alerted to the problem and both sides consulted and decided that the best solution in the interrim would be something that had been done previously, disconnecting FARICE and thus forcing all connections through the backup line, DANICE, which appeared to be operating normally.

    Unfortunately, the problem was even worse on DANICE. What appeared to be normal operation was only normal up to the data logger. Once it actually got to the flight tracking software, the messages were being refused, and corrupted messages being sent in the other direction. So while BT was working on getting their system fixed, flight control managers were being forced to basically manually dig up ATC messages and copy-paste them off to the air traffic controllers (as much was handled through voice as possible as well).

    But it got even worse. A totally unrelated communications network, Datalink, decided to misbehave during all of this, which may or may not have been due to the Shanwick problems. On the Iceland side, the general solution is to force a switchover to the backup system. Which was done... except a critical component on the backup system immediately crashed. Repeated attempts to switch and ultimately switch back caused even more problems for the air traffic controllers.

    Eventually the fixed FARICE line was brought back up, Datalink back online (with the switchover-crash problem postponed to be investigated during a low-traffic timeperiod)

    It's terrible that there were so many delays, but these are extremely complicated systems with a challenging task, built up over decades with tons of computer components, protocols, lines, routers, radar systems, transmitters, and on and on, scattered all over the world. On a weekend. Everyone was scrambling and doing their damndest to fix it as soon as possible. It should also be noted that it was never a safety issue - even in the absolute worst case, air traffic control could go all the way back to the old paper-and-pencil method.
