SNIP:
The other 'secret' about airline flying is that the maximum allowable
takeoff gross weight for each flight is always calculated on the
ability of the airplane to make the FAA-mandated climb profile after
losing an engine at V1 speed and safely clear all the obstacles on the
way. In Denver in the summer the 727s usually had some seats blocked
off due to this weight restriction. None of those hairy KC135 max
gross 'wartime' weight takeoffs!
