North Korean media hailed the might of its air force on Tuesday, claiming that it brought South Korea and the U.S. to their knees with a show of force on Nov. 4 in which it previously claimed to have mobilized “500 fighters of different kinds.”

“The enemies once again kneeled down in early November when our air force's large-scale all-out operation was carried out,” ruling party newspaper Rodong Sinmun said in an article celebrating the annual Day of Air Men.
