A Delta Air Lines plane carrying 139 passengers made an emergency landing at John F. Kennedy International Airport and officials say no one was hurt.

A spokesman for the Atlanta-based airline says the crew received an indicator light warning of possible problems with the airplane's hydraulics, which power its wings and landing gear.

The MD-88 plane was headed from Orlando, Fla., to LaGuardia Airport. The spokesman says the five-member crew decided to land at JFK as a precaution because JFK has a longer runway.

The plane landed safely at 4:42 p.m. Monday. Officials say they're checking the plane's systems.
