Being a Gringo, I am at a loss
but
DOT...could that mean, FLY A DOT HIGHER? As in the ILS? Maybe someone wanted to fly the glideslope a DOT HIGHER to avoid wake? Maybe the 767 was on the high side too?
I do recall a much bigger plane than a Lear getting flipped and crashing...DC10 in front of a DC9...the DC9 lost.
OUCH.
