Some info for all of you...

1. There has NEVER been an autoland of a US Space Shuttle (the Soviet Buran's only flight was unpiloted so of course it did.)

2. The shuttle does have the capability to autoland in theory but people have to work the gear at a minimum so it isn't like the shuttle could be unmanned.

3. In the early shuttle program they were trying to test the autoland to ever lower altitudes before manual control was started and on STS-3 (the only landing at White Sands) the autoland took it down to about 50-100 feet but was way fast and off profile and because of it they had two problems, at the time they lowered gear based on speed not radar altimeter (which they since changed) and so the gear only was down and locked less than 2-3 seconds prior to touchdown which was dangerous and second the human controlled flare and touchdown was poor since they "took it" so late and off profile and later actual rerotated almost striking the tail. The whole incident caused a large scale review of landing procedures and there is a big 40-50 page blow by blow of the approach problems done up as a NASA study after the flight.

Here it is: http://spaceflightnow.com/shuttle/fe.../sts03_qt.html

4. After the STS-3 problem they never again took it on auto so low and now in the modern shuttle program most commanders hand fly from 100,000 feet down including the entire HAC (heading alignment circle) and landing. Often Commanders will allow the Pilot (ie. the Co-pilot) to fly part of the HAC as a courtsey. It remains a commander preference where exactly they begin to fly it but 100k is the common number.

5. 22 degrees GP is common I think and a slight reduction in GP while on final at around 5-8k is normal, flare is far later while still a few hundred feet in the air.
