I'm now somewhat seriously confused by trying to follow all of the contributions to this thread.
I have now considdered those "hot and cold nozzles" of the Harrier and, how we have managed to balance several tons of airframe upon a vertical stream of thrust; all of that "inlet drag", or whatever each individual might wish to call it, has stopped the aeroplane from plummeting to earth by redirecting the thrust path into a "more useless path" other than a "forward thrust" direction!
I've no wish to become "Devil's advocate", but...
Do forgive my lack of scientific understanding of what has been previously debated, but, "How does that work"?
