I remember that "chest vibration" effect when I was a kid at the 1978 Farnborough Air Show. Concorde made a touch and go on that day, and the sound was body shattering!

No other aircraft is capable of that. Not even the huge and ugly A380.

Ironically, with the better simulation of air mass which is allegedly on the way in the new MS flight simulator, I'm kind of hoping that eventually someone will get around to making a Boeing 707, 727, Douglas DC-8 or even a Convair 990 for that sim which has a genuinely good stab at simulating the management of the engines with the EPR settings, so one day those rather pricey 727 and 707 manuals I bought might come in handy and we'll be able to actually use those paper charts realistically to calculate take off settings.

The Aerosoft DC-8 already does match paper EPR charts to actual EPR settings in the sim, so if you're looking for that type of simulation, there it is.

Your post reminds me....Over in the Aerosoft forum the developer recently made a few hints that he might be producing some sort of non-Boeing classic jetliner for the new sim.

Anyway, my point is, if his attention to EPR detail is anything like it was with the DC-8, we may be in for a treat with something new, whatever it turns out to be, given the "better air mass simulation" we might see.

Hope that helps you understand it all a bit better. It's really not as complicated as it appears at first and it's kind of interesting to learn about all that stuff if you like aeroplanes.

Awesome, excellent explanation.  You condensed it down so that non-experts / non pilots can understand what de-rated takeoffs are all about.,  Great post.
