Great shot! What kind of camera and lens were you using?

In this picture, a couple feet back on the chine on both sides, there is a
blunted, pushed in area on the chines. Almost looks like the nose ran into
a round hole in a wall, and dented the chines. Of course, I doubt that
happened.

What is the story with that? I had never noticed that on other models of
the 71. Is that damage, or a feature, and if it is a feature, what is it
designed to do - if you or someone knows?

The original aircraft from which the SR-71 sprang was the Lockheed A-11. It
then morphed into the YF-12. Finally, it became the SR-71. The A-11 and the
YF-12A sported a different nose/chine configuration than what you finally
got to see on the SR_71.

Not that one it is an sr71 I believe that is a later modification

Hmmmm....curious/strange. I went and had a look and you are right. My foggy
memory failed me. The A-11/YF-12A nosecones were different but not like what
is present in that image. It almost seems like an intermediate morph between
the A-11/YF-12A and the SR-71.

The other possibility is that someone bent it.

Those "dents" are the modification for the ECM antennas.
(Electronic counter measures)

This photo is the YF-12A and the chine mod is for the ASG-18 fire
control radar. to insure directional stability for the chine being cut
three small fins were added to the rear of the underside of the YF-12A

I thought they were where the ground crew were supposed to push if the
brakes failed...

I just dug this one out of an old file. The SR-71 at Barksdale AFB in
Louisiana has the same indentions.
