According to a recording from the plane obtained by CNN, the pilot told the air traffic control tower: 'No need for crash fire rescue, we just need to run a checklist. We had a window come open.'
The Boeing 737 was rolling down the runway at a 'low speed.'
Windows in the cockpits of passenger aircrafts can be opened to allow for extra air circulation while the plane is still on the ground.
