Zooming around
Someone mentioned the excellent power-to-weight performance of the 757.
Well, as you probably all know, the Ruskies did their own "Chinese Copy" (?!) of the B757 , the Tupolev 204. (As an aside, I suspect that might start selling well in the West soon.) Same engines as the B757, and very similar airframe.
However, they didn't initially have an engine thrust de-rate system, so every take off was at rated thrust. My informatant was on the flight test aircraft and still shudders from the thought of the take-off performance with an empty aircraft.
However, I hear that all of the production now have a thrust management system.
