Surely that depends on the initial speed into the turn, the force of the turn, and a few other bits that escape me at the moment. Unless it's turn radius is huge at any speed?

It's in orbit, so it's changing its vector more than turning.

Also wright pat in Dayton has a 71 too, iirc from my last trip there.

That makes more sense! I should've guessed by it's looks.

Back to the Blackbird, I've seen them at Mildenhall and Lakenheath airshows in the late '80s and very early '90s but disappointingly only on static display, and I've seen it fly once at Alconbury airshow around the same times.

Living where I do I've seen a lot of different aircraft over the years in their day-to-day flying, but not this beauty.

... it is curiously overdue to RTB, unless there was a clandestine landing within the last couple of weeks.

I caught an SR-71 on static display at an airshow just before they came out of retirement in '93. The Kalamazoo Air-Zoo has a B variant.

I told him that it did look slightly different and he asked why might that be I took a guess and told him it must be an A-12 he was pretty impressed and showed the all the data about the plane.I still cant put my finger on what it was but that A-12 did look slightly different than an SR-71 I think it is the nose on the A-12 it is a little wider some of the dimensions are slightly different as well I have always had a keen eye for aircraft design.

The SR-71 has wider canards on the nose than A-12. IIRC it had to do with achieving extra lift, but don't quote me on this.
A-12

Gaaah! Too big! Too big! Slow computer crash!

Oh sorry about that, I could resize the images if it is an issue.

My seven-year-old computer is fine with it. I just wanted to say something funnier than "I hate scrolling sideways and I can't see the whole picture".

Herr-Berbunch · 04-18-12, 10:42 AM

Err, the biggest difference is the A-12 is single seat. This makes it slightly longer too.

And a canard (quack-quack) is a separate fore-plane, those running along the side of both are chines.

What? I had a very geeky childhood with aeroplanes

Depending on your browser you could just hold ctrl and use the mouse scroll wheel to zoom the page in our out.
It works for opera and chrome, fairly sure firefox and the latest internet exploder support it as well.

The most noticable difference for me was that on the A-12 the chines stop abrubtly rather than tapering into the fuselage. And yes, I knew what they were long before reading your post.
I was around back then.

Silly goose. I'm just lazy and don't like to scoll at all.

I have a bigger monitor. Everything is amplified, including the pictures.

Steve the SR-71 picture you chose is a really good one because it illustrates the fuel seepage very well you can tell that that photo was taken shortly after the first in air refueling and you can see where the seep points are for the fuel cells.The area around the fueling receptor is clearly from the the fueling booms over spray.

Of course it might also have just come down from higher speeds and the seepage have been caused then though I doubt once it got warmed from higher speeds it would have cooled down enough for the seepage to occur again as long a a pane is flying it is generating some friction and would have more heat than an idle plane on the ground.That is why I would say that the bottom photo shows the seepage from take off to the refueling point.

According to the guy at that museum the A-12 had a slight blue tone to its black paint that the SR-71 did not have.He did help restore that A-12 so I assume that he must have been correct that the two planes had slightly different paint.

Here is a link all about the A-12/SR-71 it has a number of good wraparound photos of every A-12/SR on display in the US by looking through them you can really see the differences in shape interestingly it seems that for the D-21 drone program there was a hybrid M-21 an A-12 with a SR front end made that was used for training purposes it says that that made only two M-21s.
