Bloom you are happy to speculate that "they pissed it all away", "deep stalled" (sic), "mismanaged a manageable incident" and "screwed the pooch" on what little evidence there currently is yet it's not for you to speculate on training standards...wtf?
As for the old stretching the glide scenario, we need to consider that this probably saved those few. Turning that last bit of airspeed into momentum away from buildings and admittedly losing glide distance afterwards may have prevented a 911 type impact.
