Yeah, but the SR71 is 107' long, so if someone is guessing about its replacement, then 110' sounds reasonable.

Almost all of the things I can find on the Aurora, indicate a high-flying hypersonic aircraft. It still used engines of some sort to create thrust to move it forward and create lift.
Here is a story from a former pilot I found while trying to see how slow an SR71 could fly, as it's the closest thing we know of to our hypothetical Aurora (I've edited a lot out):

As we scooted across Denmark in three minutes, we learned that a small RAF base in the English countryside had requested an SR-71 fly-past.
Walter told me we were close and that I should be able to see the field, but I saw nothing. Nothing but trees as far as I could see in the haze. We got a little lower, and I pulled the throttles back from 325 knots we were at. With the gear up, anything under 275 was just uncomfortable.
The longer we continued to peer out the window and circle, the slower we got. With our power back, the awaiting cadets heard nothing.
As I noticed the airspeed indicator slide below 160 knots, my heart stopped and my adrenalin-filled left hand pushed two throttles full forward. At this point we weren't really flying, but were falling in a slight bank.
Finally, Walter looked at me and said, "One hundred fifty-six knots. What did you see?" Trying to find my voice, I stammered, "One hundred fifty-two."

So, if true, this guy got an SR71 down to around 155 knots. That's still not hovering, although he said it may have been very quite.
I don't know how to reconcile the photo with the story of the photo. If it's some super-secret US craft that had problems and got low enough to be seen and photographed, then either if can float in the air before rising up in a vertical takeoff, or the story behind the photo is not accurate.
If the story is not accurate, then where does that leave the photo.
And if the story is accurate, then what technology is at work, that is still completely secret 30+ years later?
