Operations were back to normal at Logan International Airport on Wednesday, after two days of delays caused by a faulty radar antenna.
Workers borrowed an antenna from an airport in Bangor, Maine, to fix the faulty equipment, said Federal Aviation Administration spokeswoman Arlene Murray.
Some minor flight delays were reported on Wednesday because of heavy rains.
Air traffic controllers began seeing phantom blips on their radar screens over the weekend that they knew were not incoming planes.
They switched to a long-range backup system in New Hampshire that required a greater distance between incoming planes, which delayed incoming flights for up to four hours Monday and Tuesday, the AP reports. A.M.
