I’ve read stories before about air marshals intervening on the ground. They shot and killed a mentally ill person on a jetway in Miami I think. And an air mashal once did CPR on a heart attack patient in an airport gate area.
But I think this is the first I’ve ever heard of an air marshal actually intervening in flight. And it sounds like they didn’t manage to do anything that any other able bodied passenger would have been able to do–another datapoint for my “FAMs are useless” hypothesis.
