When i learnt to fly (many moons ago now) it was on the c150 and i was taught an alternative to sideslipping for loosing height, if you need to come down VERY quickly, ie because of to high on a forced landing, kick on FULL L rudder then immediately FULL R rudder so the a/c fishtails, keep doing this until you are at the height you want, you don't need to worry to much about stalling/spinning as long as you keep to normal glide speed and you can do it with full flap, but the ROD is very impressive.
n.b. the B757 side slips very nicely.
