Ya, that's right. I can't remember the call signs that NASA used on the TR-1 / U2, and their brief stint flying the SR-71.

My point exactly. Same thing at the equator.

RB-57F was "Snipe."

I generally saw winds around 5-10 knots max above 60K

Currently, that would be "NASA 806" & "NASA 809".
And they are ER-2's, not U-2's/TR-1's.
For the record, the TR-1 designation went away in Oct 1992.

Time flies by.............

My father was working for NASA as the director of the High Altitude Test Research at Moffett field. They were phasing out the U-2 c models and was having a hard time getting NASA to fund a new jet. He had talked to Lockheed and they came up with the ER-2 designation, ( Earth Resources -2) and had a production slot but NASA was dragging their feet. He finally got ****ed and thru his Visa card down saying " G-dmit just charge the thing on this". Two weeks later he got the funding and ended up with 2 ER-2's.

As a tanker clown, for those who got to see the SR-71 air refueling charts / turn radii ... it is really freaking cool how far the turns are started in order to marry everyone up.
