Just spitballing, but there's a non-zero chance NVGs were in use in the helicopter.
It sucks that the best part of this is the airplane was a CRJ, not a larger airliner. Most all those passengers would have survived the initial collision and been aware during the fall to the river.
I feel rage.
what is a “non-zero chance”? Is it the same as a chance or more like a certainty? Confused by what seems like an American expression.
