This week, a new monument was unveiled at Arlington National Cemetery in Virginia.

The Vietnam Helicopter Pilot and Crewmember Monument was revealed off and honored amid a crowd at the hallowed grounds just outside Washington, DC, on Wednesday, April 18.

It’s dedicated to the pilots and crew lost over the skies of Vietnam.

“Over 12,000 helicopters — Army, Navy, Air Force, Marine Corps — carried the flag to the enemy. It is only fitting that our monument we dedicated today bear the iconic symbol of the UH-1, Huey. Over 10,000 were built, for that war, and 7,000 saw service in the theater, flying over 7.5 million flight hours — more combat time than any other aircraft in the history of warfare,” said retired Major General Carl McNair, former Army helicopter pilot, while addressing the crowd at Arlington. “Over 3,000 of those aircraft did not return. And 4,901 of our pilots and crew members gave their lives.”
