The pilot of a regional airliner flying over North Dakota made an unexpected sharp turn to avoid a possible midair collision with a military B-52 bomber that was in its flight path over the weekend.

The Federal Aviation Administration said on Monday it is investigating a near miss between a SkyWest Airlines jet and a U.S. Air Force jet over North Dakota last week.

The pilot of the SkyWest flight apologized to passengers after having to make an "aggressive maneuver" to avoid what he identified as a B-52 bomber near Minot.
