A United Airlines flight made an emergency landing Tuesday afternoon at Philadelphia International Airport after a small engine fire.

None of the 75 people on board was injured, though a passenger with a reported history of heart conditions was hospitalized, authorities said. A brief ground stop was issued for the airport while the plane was towed from an active runway.

United Express flight 4882, which took off from Raleigh-Durham International Airport and was bound for Newark Liberty International, landed around 3:50 p.m.

Passengers were evacuated onto the runway as the fire was extinguished and bused back to terminals. One of the engines on the twin-turboprop Bombardier Dash 8 caught fire, an airport representative said. - Matt Gelb
