Yesterday I was watching a program on the Discovery Channel called "How It's Made" relating to windshield wipers.
They stated that "even the Shuttle has windshield wipers".
As far as I know, it doesn't.
Am I wrong?

Thanks Jim.
Didn't think so.

Maybe they were put on to wipe off the 3000 degree plasma

Hmmm...wonder if the TV show is referring euphemistically to the plasma "cleaning" stuff like SRB sep motor residue off the outer panes during entry.

Here's the video (2 minutes in):
And here's the only "source" I could find.

That's it dsl!
It really makes you wonder where they get their facts from.
I have written an e-mail to them informing them of their mistake and a suggestion that they edit that episode.

Ah, well, then no need to give them the benefit of the doubt. Jim and Danny are right and no idea what either the TV show or website are referring to, but sounds like a "lost in translation" issue for both.

It has been quite a while since I have been in an orbiter or the SMS (shutte mission simulator) but I think the wiper blade control was an adjustable switch located on the same arm as the turn signal controller...of course I might be mis-remembering...

Reminds me of Ted Striker:
Lets see...Altitude, 24,000 feet...level flight, speed 520 knots. Course, 0-9er-0...trim, mixture...wash, soak, rinse, spin...

So to carry on a tiny bit with frivolous TV-related questions, does the orbiter exclusively use Michelin tires? I know Goodyear has a heavy hand in aviation tires.

I believe they only use Michelins, at least all of the ones I've seen were. But I'm not an orbiter guy, so maybe someone else on here can confirm that.

I believe Michelin tires are the only ones certified and that they have left, but the certification on them is about to expire on the cord material and it needs to be adressed for shuttle extension.

Can someone explain the numbering system and naming used for the Shuttle solid rocket boosters?
The ET numbering I get (discrepancies explained above), but in particular I am confused by the difference between a "Solid Rocket Booster set" and "Reusable Solid Rocket Motor Set" as mentioned in Chris' recent article about STS-132:
"For launch, Atlantis will use External Tank ET-136, Solid Rocket Booster set BI-143, and Reusable Solid Rocket Motor set 111"

An SRM is not an SRB. An SRB is consists of an SRM, aft skirt with hydraulics and sep motors, fwd enclosure, nose cone with recover systems and sep motors, system tunnels and avionics and fwd and aft ET attach points.

I was wondering after the shuttle jettisons the external tank does it completely burn up before hitting the indian ocean or does some debris end up on the ocean floor? If the second case is true there must be a lot of junk after 120+ missions.

Some debris makes it all the way to the ground. Designing ascents to make sure this debris doesn't hit anyone is a very big job that NASA does very well. Even during aborts, the debris is put in the water somewhere.

High inclination, direct injection, no OMS-1 puts the ET into the Pacific, right? Indian Ocean was earlier in the program.

Believe it's the Pacific for direct insertion on low(er) inclination flights, too, such as the next one. The tanks re-entered near the Hawaiian Islands on a couple of occasions that come to mind -- STS-41C and STS-37, which were both direct insertion.

IIRC low inclinations go into the Indian ocean. I would not bet money on this though.
