A British Airways plane bound for San Francisco, California made an emergency landing at Ireland's Shannon Airport Saturday, officials said, according to AP. The plane was a Boeing 747 en route from Heathrow Airport to San Francisco with 347 people aboard, Shannon Airport spokesman Eugene Pratt said. BA said 328 of them were passengers. «At about 6:45 p.m. Irish time (1745GMT) there was some sort of emergency concerning the hydraulic system,» Pratt said. «It landed safely at 7:25 p.m. (1825GMT). Apparently the situation is rectified and they're fueling up to resume the trip.» BA described the emergency landing as a precaution, saying in a statement that the aircraft suffered a «temporary hydraulic indication defect» but that the pilot was able to reset the system. A spokeswoman for the airline did not immediately return calls or e-mails seeking additional comment on the incident.
