They're saying Logan Airport in Boston is open.

Notes made from news - some may repeat what others have said. Please forgive spelling errors:

The plane was an Airbus A-300
Flight 587, flying from JFK to the Dominican Republic
246 souls on board (includes 9 crew)
The plane crashed 10 miles from Kennedy airport, about 2 minutes after scheduled takeoff, in the Rockaway section of Queens. It crashed at 129th St and Newport in an area known as Bell Harbor
So far, the FBI do not suspect foul play. All NYC tunnels and bridges are closed.
