The pilot then turned the plane back to Philadelphia. The airline says five people were taken to hospitals and their conditions weren't known, but none of the injuries appeared life-threatening.

US Airways spokesman Bill McGlashen says the seatbelt sign was still on at the time of the turbulence, which occurred when the plane was at 17,000 feet.

Airport spokeswoman Stacy Jackson says another plane took off at 8 p.m. Sunday to carry the passengers to Orlando.
