Qatar B777 collision probe focuses on intersection riddle
Investigators have revealed that a departing Qatar Airways Boeing 777-300ER overran the runway at Miami airport before becoming airborne and striking approach lights as it climbed away. The inquiry into the accident has disclosed that the captain chose to depart from the T1 intersection of runway 09 despite carrying out the calculations for a full-length runway departure, and despite a prohibition on intersection take-offs from this runway.

four, so called "pilots", in the cockpit and no one "noticed" something wrong with that decision by looking at the "taxi position" displayed on the instrument and worse..none noticed or even became "doubtful" about the possibility (a real one) that the huge 777 (372 tons) could have overun the runway and hit whatever was "after" a runway...ENDS!!!! Am I wrong?? if so, please somebody tell me why.

Thanks, much more detailed
The report is stunning to me in the summary info provided, in that the captain could understand that the software architecture "09#T1" was referring to a full length departure and that intersection departures were not permissible from that runway. Then as he sees a taxiway sign showing the T1 intersection, he "decides" that the jet could depart from the intersection T1. Apparently, he reasoned that the T1 in the architecture display meant intersection T1. Later, when questioned, he couldn't recall how he came to that decision!
It appears to me that he had less than a full understanding of what the software display was telling him since he was so easier swayed into attempting an intersection departure. No excuse for that attempted takeoff.

A link to AVHerald posted by MH370 has more detail. The EFB display only went as far as T1 and did not show the taxiway to the end at the zoom level selected. Maybe overreliance on technology and underreliance on piloting and situational awareness skills are contributing factors.
I agree with you, Joel.
Also, maybe a good company procedure would be to have one of the two displays always showing the big picture except for quick selections of the zoom by the "un-zoomed" pilot for resolving concerns at very complex intersections, for example. A quick sanity check by the captain before committing to the T1 intersection departure would have been to view the entire runway, it may have saved a rug dance in the chief pilots office.
