It's done routinely. Maybe not on the shuttle, but airliners, military jets, about anything. And with the shuttle, a one shot landing, I'd trust the computer, as not getting distracted, able to monitor more information, and react more appropriately.

Carrier landings at night by fighters can be done by computer. Those, I understand, are tricky, and some good pilots have said they'd rather get out of the service than do one more of those manually.

Some airplanes need to have operating computers just to not come apart in the air. Why? 'Cause people can't react that rapidly.

Personally, I'd rather have the computer doing it, with human backup. Not a ditch I'd die in, and I don't anticipate ever having any real choice in the matter.
