AFAIK Concode only uses ~80% thrust on takeoff due to vibrations engines create and risk of overheat. Also fuel gets pumped around to change CG, it is a fascinating piece of machinery.

It's all in that thread :) The 80% limit was only on one engine, due to vortex issues. The others had to be at "100%" and full afterburner to get off the ground. The actual volume of fuel flow for a particular power level was also determined by an analogue computer measuring the inlet air temperature and pressure. http://www.pprune.org/tech-log/423988-concorde-question-4.html#post5887403 http://www.pprune.org/tech-log/423988-concorde-question-4.ht...

Relevant distraction: Nice in cockpit vid of pre takeoff CG and fuel transfer checks, take off, and after checks. 10m. http://www.liveleak.com/view?i=16a_1231096566 http://www.liveleak.com/view?i=16a_1231096566 Low light takeoff, because pretty: https://www.youtube.com/watch?v=l7mt6AKKhq4 https://www.youtube.com/watch?v=l7mt6AKKhq4
