The 5-foot-long hole tore open in the passenger cabin roof area shortly after the plane left Phoenix for Sacramento, Calif., Friday afternoon. None of the 118 people aboard was seriously hurt as the plane descended from 34,400 feet to a military base in Yuma, 150 miles southwest of Phoenix.
Since then Southwest grounded its 79 other Boeing 737-300s and began inspecting them.
Sunday night, another Southwest Boeing jet was diverted, this time because of a burning electrical smell in the passenger cabin, Southwest and Los Angeles International Airport officials said.
