(AP Photo/Lynne Sladky) (Newser) – Just a few days ago, American Airlines confessed it had mistakenly allowed an aircraft not certified for long flights over water to make the trip from LA to Hawaii. Today the airline faces another problem: Unexplained technical issues forced it to temporarily ground planes at three of the country's most hectic airports, CNN reports. Chicago's O'Hare, Dallas/Fort Worth International Airport, and Miami International Airport were all affected during the two-hour glitch, which ended about 2pm Eastern, reports AP. The FAA notes in a tweet that the stoppage was due to a "computer issue." International flights weren't affected, a spokesman tells Reuters.
