As this is my first post in this forum, let me please begin with stating that I am not a pilot but coming from the medical sector, and having some skills in TRM/CRM course systems as a coach for clinical teams.
Having said that, the question I'd like to ask you as the experts: Could the earlier GA have indeed have had a negative impact on the outcome of this tragic event?
I am thinking in a way that the behaviour of the Aircraft might not have fitted the pilots "mental model " here.
I guess that after being in the holding for 2+ hrs, it must have been significantly lighter than before. Could it therefore play a role that the pilots expexted a similar response to control inputs like in the first GA, but the now lighter aircraft reacted differently?
Humans tend to interprete situations under stress following their previous experiences, and this might have prevented the crew from judging the current situation approbately?
