KheSanh Descents - Try It!!!!

"I will try and get hold of some airshow videos, and see how it is done". "And then try it myself". !!!!!!!
These descents are not for the trying thereof. On a calm day you could end up with a touchdown too far into the runway. With any wind at all you will always have a very high rate of descent and a low nose attitude - get it wrong one way and you will arrive nosewheel first with high ROD, get it wrong the other way and you will flare too early, float and risk stalling in. On a strong wind day you may end up pointing into the undershoot and risk stretching the flare to the runway - always a disaster.
Some other comments on this thread are correct - the airshow demo is from about 1000 feet and looks spectacular but the real event starts much higher in order to stay away from the bad guys.
