Actually according to the charts departing from the intersection of rwy 15 only costs 200 feet. Although depending upon technique a heavy backtrack would only pick up an extra 100 feet or so it is always preferable to have available runway in front then behind you. Regardless I would question why any heavy would not use the backtrack unless their were compelling reasons for not doing so as that is the norm.
I’m rather surprised that you are partially blaming the airport facility for this accident, as this is a real stretch in my opinion as is your reference to the Swissair accident.
However you are perfectly correct in stating that all the airport improvement taxes that our passengers pay should be used for infrastructure improvement. But we both know this is never going to happen as the authorities view aviation as a cash cow.
