Granted, it’s a twin engine helicopter and could have taken an engine out and flown off into the night but a catastrophic tail rotor failure would have been problematic at that height AGL and the people.
I dispersed crowds in Vietnam with a Cobra helicopter but was never tasked to do that here in the USA. Later in the Army Guard flying the Chinook and also Huey, our missions often involved lifesaving flights and not with a red cross painted on our aircraft. My how times have changed!
