I just watched the stablemate to the crashed aircraft depart from YHML on a charter to EN. It was airborne half way down 35 flat climb out graceful, gear up before threshold and flew well with 8 or so souls on board.
Different pilots lift off at different distances though. I can remember watching on separate occasions two pilots flying the same aircraft off the same runway with the same load on board. One would be airborne halfway down the strip while the other would hold it on the ground for a lot longer. The latter used to scare the crap out of me sometimes, especially on the shorter of the two strips!
