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.

The B-52 crossed the grandstand at the fairgrounds at 7:50 p.m. and headed west to clear the tower’s airspace before returning to the base.

Ground squirrels have proliferated in Minot, North Dakota's fourth-largest city. They've burrowed everywhere from vacant lots to school grounds, residential areas and the downtown area.

The North Dakota State Fair encourages fairgoers to purchase tickets directly from the fair website to avoid falling victim to scammers.

The North Dakota State Fair is saying ‘thank you’ to those who have served, as well as those who are currently serving, and to the families who support them every single day.

"So sorry about the aggressive maneuver, it caught me by surprise. This is not normal at all," the pilot told passengers.

The Boeing B-52 Stratofortress is America's oldest bomber and has been flying for the US Air Force for 70 years.
