Software Glitch Delays Flights

Susan Hall

Hundreds of flights were delayed Tuesday after a software malfunction at an Atlanta-area facility that processes flight plan information, reports InformationWeek.


A backup facility at Salt Lake City took over the work, but was overloaded as multiple airports kept refiling their flight plans. Once the duplicated flight plans were entered manually, the Salt Lake problem was cleared up, according to The Los Angeles Times.


The FAA said it was never a safety issue and communication was never interrupted between plane and control towers. The airports hardest hit were in Chicago, Atlanta, Boston, and Washington D.C., with delays of 90 minutes or less. The agency called the problem "unprecedented," saying it was different from the glitch that caused delays last week.


The FAA doesn't plan to bring the Atlanta system back up until it better understands what went wrong. It ruled out hacking as a possible cause, though, according to The Washington Post.
