A Boeing 747 cargo plane made an emergency landing Thursday night after it was seen spewing flames in the night sky over Miami.

The Federal Aviation Administration, which is already investigating Boeing after an Alaska Airlines flight was forced to make an emergency landing when a door plug fell off the fuselage midair this month, said in a statement Friday that it will look into the latest incident on an Atlas Air flight.

Atlas Air said in a statement Friday that one of its planes landed safely after an unspecified problem with one or more of its engines shortly after takeoff.
