At least five bomb threats were phoned in Tuesday against flights originating or landing in the U.S., government sources have told NBC News.
Four of the five flights landed already, according to government sources. The fifth, Korean Air Flight 23 from Seoul to San Francisco, is scheduled to land Tuesday afternoon.
Over the past two weeks, hoax threats have been made against almost a dozen planes, and none of the threats made Tuesday were deemed as credible.
Delta Flight 55, from Los Angeles to Atlanta; United Flight 995, from San Francisco to Chicago O’Hare; and Volaris Flight 939, from Portland, Oregon, to Guadalajara, Mexico had already landed. U.S. Airways Flight 648 from San Diego was met when it landed in Philadelphia with a bomb squad that searched the plane and passengers before giving the all-clear.
