A historic cemetery has a new memorial honoring the 134 people who died in a midair plane collision over New York City 50 years ago.

Bagpipers played "Amazing Grace" as about 150 people, including relatives, watched the unveiling of a granite monument on Thursday. A bronze plaque bears the names of the victims of the Dec. 16, 1960 crash.

The collision of a United Air Lines DC-8 and a TWA propeller plane left a legacy of improved air safety in its wake.

The United plane destroyed at least 10 buildings when it crashed into the Park Slope neighborhood.

The memorial is at Brooklyn's Green-Wood Cemetery.

It is the final resting place of many notables, including composer Leonard Bernstein.
