No one was injured when a bullet struck the right side of an Indianapolis-bound Southwest Airlines flight as it prepared to take off from Dallas Love Field.

There are still more questions than answers as to how a Southwest flight departing for Indianapolis was hit with a bullet Friday night on the runway at Dallas Love Field. No one was hurt on board, but concerns are being raised about a larger security threat.

There were no reported injuries on the plane, which was struck while preparing for takeoff, Southwest Airlines said. The plane safely taxied back to the terminal after the incident.
