On the tenth anniversary of TWA Flight 800 families, friends and officials gathered to dedicate the last piece of the memorial. Two hundred thirty people died on the flight from JFK to Paris, and Newsday (which has an excellent section on the 10th anniversary) describes the final piece as an "abstract rendering of a lighthouse" made of black granite "that looks out over the Atlantic is intended to serve as a metaphorical beacon." The rest of the memorial, which includes a granite wall with victims names and benches, was dedicated in 2002.

Kyle Gustafson has a set of photographs from yesterday's 10th anniversary ceremony on Flickr. And there are still questions about what happened to Flight 800, with people hypothesizing it could have been a terrorist bomb or a missile strike.
