Okay, this may be a really dumb question, but what the hell, I'm going to ask it anyway.
Concorde's four Olympus engines outputted 169 kN each (wet), pushing fuel and air out the back at an enormous rate and therefore pushing the craft forwards rather quickly.
In order to achieve this it's dragging in (I have no idea how much but it must be lots of) air at the front of the engine.
In what sense, if any, can Concorde (and other jets) be said to have been propelled by the suction in front rather than the exhaust behind. Are they secretly the same thing? Is the question meaningless? Am I missing something terribly obvious?
