that less than 30% of unstable approaches resulted in GA!!
I think this is what the "scary" statement refers to.
Its well documented as the the hazards of landing off an unstable approach can be (in particular engines not spooled up). Okay the scary, thing might have been a bit dramamtic, but he's got a point.
ANY company has to draw a line in the sand as to limits for stabilised criteria, and ok we've all milked it at times, and it can be a pain in the a$$, but the reality is it is unsafe to continue to land in such a condiotion.
If you don't agree, have a quick look at the habsheim 320 going into the trees in a cloud of smoke. Unusual scenario yes, but graphic example of an abort from idle thrust.
