The woeful R/T during this event will certainly be a factor.
Crass and cavalier radio chatter is SOP in the good 'ol US of A. Farm animal noises on guard, trying to sound cool with every transmission with ATC. It's a bloody disgrace a lot of the time.
'roll the trucks', 'we're going in the hudson', 'she's running hot', '5 to 10 in the climb', 'hows the ride at three five oh'.
It's an embarrassment. Some of these clown should have a go at flying outside the US and see how well that goes.
