NEW YORK CITY Kennedy. The Challenger. 9/11.
You may remember where you were when you heard about, witnessed on television, or maybe in person, the Nov. 23, 1963, assassination of President John F. Kennedy; the Jan. 28, 1986, explosion of the space shuttle Challenger; and the Sept. 11, 2001, terrorist attacks.
A visit to Sept. 11 memorial is a gut-wrenching, emotionally disorienting and profound reminder.
It is also essential.
The Sept. 11 memorial was dedicated May 15, 2014. It opened to the public May 21, 2014.
