CNN reports that the co-pilot suffered scratches and a sprained wrist. A flight attendant was also hurt. No passengers were injured.
An investigation into the incident is underway.
This comes nearly a month after a woman died after she was partially sucked out of a window that broke during a Southwest Airlines flight on April 17.
Southwest Flight 1380 departed from New York's LaGuardia Airport and headed to Dallas when part of the plane's engine broke off mid-air. Investigators believe debris from the crash broke part of the window, pulling passenger Jennifer Riordan halfway out of the plane.
She later died of her injuries.
A cause into the Southwest Airlines crash is still underway.
