The NTSB gave an update Friday on the devastating crash in Washington, D.C., between an American Airlines plane and U.S. Army Black Hawk helicopter.

It has been a month since the mid-air collision over the Potomac River killed 67 people and this Sunday, the community will honor the lives lost with a ‘Legacy on Ice’ tribute at Capital One Arena.

Nancy Kerrigan, Kristi Yamaguchi, Scott Hamilton and Brian Boitano are among the skaters participating in the benefit event.
