The evasive action an airline pilot took to avoid a B-52 bomber in the skies over North Dakota has focused attention on the way small airport towers are often run by private companies without their own radars.

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 Friday incident is detailed in a video taken by a passenger and posted to social media as Delta Flight 3788 approached the Minot International Airport for landing.
