LHC Shut Down Again — By Baguette-Dropping Bird

Philip K Dickhead writes "Is Douglas Adams scripting the saga of sorrows facing the LHC? These time-traveling Higgs-Boson particles certainly exhibit the sign of his absurd sense of humor! Perhaps it is the Universe itself, conspiring against the revelations intimated by the operation of CERN's Large Hadron Collider? This time, it is not falling cranes, cracked magnets, liquid helium leaks or even links to Al Qaeda, that have halted man's efforts to understand the meaning of life, the universe and everything. It now appears that the collider is hindered from an initial firing by a baguette, dropped by a passing bird: 'The bird dropped some bread on a section of outdoor machinery, eventually leading to significant overheating in parts of the accelerator. The LHC was not operational at the time of the incident, but the spike produced so much heat that had the beam been on, automatic failsafes would have shut down the machine.'"

    Further investigation into the failure of a cryogenic cooling plant revealed an unusual impediment. A piece of crusty bread had paralysed a high voltage installation that should have been powering the cooling unit.
    [...]
    A spokeswoman for CERN confirmed that baguette was responsible for the latest hiatus, but she conceded that mystery surrounded the way it got into the vital power installation, which is protected by high security fences.
    “Nobody knows how it got there,” she told The Times. “The best guess is that it was dropped by a bird, either that or it was thrown out of a passing aeroplane.”
    “Obviously this was slightly surprising. Within the team there was some amusement once they had relaxed after initial concerns.”
    The bread was discovered on a busbar - an electrical connection inside one of eight buildings above ground on the 17-mile (27km) circuit in the Swiss countryside.
    The spokeswoman said: “The collider extends over a very large area – you have to have a very comprehensive system to try to avoid problems of this kind. We’re talking about a couple of days down time.”
    Scientists hope that the temperature will be restored by around midnight tonight allowing work to continue. The failure of the cooler meant the temperature rose around 5 degrees to the equivalent of about -266C.

    A lot of things will drop on sections "of outdoor machinery". It seems that this LHC machine has been designed in such a way that will never get a chance to work.
