It flew over my house back in 93 or 94.
What it was doing flying about 1500 agl 50 miles south of SLC I have no idea
But it was a very impressive sight.
I highly doubt that. That's a 180,000 pound orbiter up there with pretty small wings. No doubt there's some offset, but not nearly enough to cancel out it's weight. In any event, the drag would certainly cancel out any advantage that you might get from the wings.Yep, kinda like floats on a float plane. It provides enough lift to cancel out it's weight.
Basically it provides additional lateral stability as the orbiter disrupts the normal airflow around the 747's rudder.What exactly do the winglet looking parts in the rear do?
Apparently what I've heard from a couple AF guys is that they don't go too high with it because they worry about possible icing with it. There are so many blunt surfaces that they fear they could pick up too much ice. Don't quote me on that, but that seems to be a good reason.Interesting how they're capped at 15,000ft.
