Firstly, the quote here is misleading (due to translation issues perhaps)? The aircraft lifted off 85m from the runway end, still on the paved surface (not beyond it, in the grass as the original quote seems to indicate)
that is what I have heard as well. translation issues, but in reality, on DEP all engine you dont have to be over the runway end by very much. A bit harrowing to watch...especially a 748
that PA 748 has had a tough time..
