December 16th is the 50th anniversary of a terrible day. That morning in 1960, 134 people lost their lives when United Airlines Flight 826 and TWA Flight 266 collided over the skies of Staten Island.

The United aircraft crashed in Park Slope, at the intersection of Sterling Place and Seventh Avenue.

On Thursday, Dec. 16, 2010, at 9:45 a.m. — 50 years to the day of the tragic crash — Green-Wood Cemetery will be honoring those who perished, both in the sky and on the ground, by unveiling a new eight-foot memorial. The granite monument will stand sentinel near the gravesite where the unidentified remains of victims have rested for half a century.

This special unveiling ceremony and memorial service, sponsored by Green-Wood Cemetery, is free to the public. Participants should gather at the cemetery’s main entrance at 25th Street and Fifth Avenue at 9:45 a.m. The service will begin promptly at 10 a.m.

Please RSVP with Isabella Vlacci at 718-210-3024.
