Both pilot and copilot executed the go around badly, This should have been a fairly routine maneuver using well rehearsed procedures.
Was this in fact a GA?or was it more a Touch & Go or Roller? That is not a trained line pilot manoeuvre. I do base training and it needs the correct sequence; it is a high speed rolling takeoff with some flap retraction and engine spool up + acceleration BEFORE rotating. If executed as such, and NOT as a GA then it would have worked fine.
