A United Airlines flight bound for Houston had to return to Phoenix Sky Harbor International Airport because of a cracked windshield.

Federal Aviation Administration officials say the pilot declared an emergency and Flight 1138 landed without incident at Sky Harbor about 10:30 a.m. Thursday.

It wasn't immediately clear how long the Boeing 737 had been in flight before the windshield cracked.

FAA spokesman Ian Gregor says officials haven't yet determined what caused the crack.

He says none of the 119 people aboard reported any injuries.
