Ron Marsico, a spokesman for the Port Authority of New York and New Jersey, said Continental Airlines Flight 99 was headed to Hong Kong when it took off around 6:30 p.m. Wednesday. Marsico said there were warnings of migrating birds in the area.
Marsico said blood was found on the nose of the Boeing 777 and around the left-wing engine.
In January 2009, a US Airways flight leaving New York's LaGuardia Airport was forced to ditch in the Hudson River after hitting a flock of geese and losing power in both engines. All 150 passengers survived.
