San Fran Fleet Week Show-- Questions

Sun Oct 09, 2011 12:21 am

I got there late-- just got a glimpse of the Osprey. Did it hover for the crowd?

How does the B-2 work, anyway? Apparently when you want the left wing to go down you open up those ruddervators or whatever they're called on the left wing-- I thought that would yaw the aircraft leftward, but I guess they spoil the lift on that wing? I was surprised how obvious they were.

The Super Hornet (what is it-- F-18C?) made a fast low pass and produced by far the most obvious shock-wave halo of the day. Seemed like the F-15 was just as fast, but maybe it wasn't quite as low? You have to hit a patch of higher humidity to get a big halo?

Both the Super Hornet and the F-15 spent a lot of time in afterburn, with an obvious glow in the tailpipes. Didn't see that at all with the Blue Angels. Do they not use afterburn or is there some reason the glow doesn't appear?

I was surprised how loud that Oracle aerobatic biplane was-- what engine does it have? What's its lowest sustainable airspeed? Seemed like he was down to 5 knots groundspeed at one point, maybe 60 degrees nose-up. He did a lot of seemingly-random tumbling, with occasional negative airspeed.

I hope someone posts the pic of the three eastward Blue Angels passing the three westward, but I fear not that many people got that one. From where I was at Fort Mason you'd have gotten all six of them with Alcatraz behind.

When I left an inbound container ship was trying to make its way past Alcatraz-- looked like the pilot was earning his money, with the Bay as crowded as it was.

Super Hornet is an F-18E or F-18F - usually they have the 2 seater do the demo at airshows, which would be the F-18F.

I think there is something about the F-18's design that gives it a better halo. I've seen a lot of great halos on F-18s at airshows but not as many on F-15s. For some reason F-18s have more moisture on them because in comparing my pictures of F-18s, F-15s and F-16s at airshows doing various manuevers, not just high speed passes - the F-18s seemed to always have the best moisture shots on the wings, streamers and halos.

I don't really have much in the way of moisture shots on F-22s.

Another good one I got good halos and moisture shots is the B-1B on high speed passes.

I've been looking on Flickr and so far I'm the only one so far that has a full cone image.
