Did I just see a C-5 Galaxy at SFO?

I'm pretty sure I just saw a C-5 Galaxy on the runway at SFO. Did I?

Riding the shuttle back home on the 101, I glanced out the window and saw a large, four-engined jet with wings mounted at the top of the fuselage. The wings pointed towards the ground at ~20 degrees, presumably because of their weight. I saw a similar airplane at Moffett Field about a week ago. Neither appeared to be taxiing.

So, can anyone confirm that this was a C-5 Galaxy? What resources are useful for figuring something like this out? Would it be possible to figure out why it was at SFO?

Finally, for bonus points, what is this wing configuration called? Wikipedia fails to mention anything in the description of the Galaxy or similar planes like the de Havilland Dash 8.

The easiest way to figure something like this out is to compare photos of C-5s and other large 4-engined military(-ish) transports, like C-17s and Antonov 124s, to your memory. Or C-141s if anyone still has one of those.

C-5s and C-17s look pretty different, but I could easily confuse a C-5 and an Antonov, and there are civilian Antonov operators. The big military transports all have to look an awful lot alike because of the demands the job places on the aircraft.

Never mind; I'd never noticed that an An-124 doesn't have a t-tail like the C-5 and 17.

Is the president coming to town? Any time he comes to Pittsburgh, a C-5 arrives the day before, presumably with his motorcade in it. We have an Air National Guard base as well as an Air Force Reserve base at PIT, and that is where the C-5 and Air Force One park when he is in town.

I think a C-5 travels with the vice president, as well.

Best answer: The wings pointed towards the ground at ~20 degrees, presumably because of their weight.

No, the wings are deliberately designed with anhedral (negative dihedral). High-wing aircraft have too much natural stability, and need anhedral wings to regain some agility.

Best answer: Bonus round: Wings like that are simply high wings, or shoulder wings.

Super bonus round: when the tip of the wing sits lower than the root, the wing is anhedral.

Best answer: I think Medvedev's in town, would that explain it?

Best answer: I get notified by FlightAware any time an An-124 or Il-76 lands at Moffett Field or SFO. Over the weekend both types landed at SFO, probably as support for Medvedev. The An-124 is probably what you saw.

It might be related to the Russian Naval visit going on in San Francisco right now:

Also, it's highly likely you saw the same plane at both Moffett aand SFO. A few days ago an An-124 flew from Moffett to SFO. I'd post more details but I'm on my phone. More later!

Best answer: There was an Il-76 at SFO on Sunday, for sure.

The airliners.net forum is awesome for this kind of minutiae, and particularly good for breaking news situations, like a plane ditching in the Hudson River. Those guys know more about the airline business than you will ever hope to absorb.

Not so much the Russian Navy, President Medvedev is in SF this week.
