Pad damage

So then, what is the cause. Is it subsidence? Sounds like some ultrasound
testing might be in order in the trench.

now, Brian.

And the disturbing increase in number and size of debris from a Tank
that was supposed to be the "best yet" (but in reality looks to be the
second worst since RTF.)

Related? Probably not, but with NASA seemingly unwilling to
acknowledge that the new Tank gave a far from stellar performance, its
hard to just dismiss the possibility.

How much can come off an SRB without it being "fatal?" Could a chunk
of propellant have come-loose and detonated somewhere in the tunnel?
How about the liquid propellants?

Or perhaps something more prosaic - like someone left something behind
in the tunnel?

The solid propellant doesn't detonate and if a chunk came out, it
would mean there is a problem with the SRM. Impossible with the
liquids.

The vibration was with camera mount and not the ride to orbit

No. Most likely the pad's aged and deteriorated enough that it's
started to fall apart under the stress. Imagine what a full-up
Ares V might do to it with 10 million pounds or more of thrust...

Way back in the 70's, I had the unique opportunity to walk through
one of those trenches. I don't remember the lining being so clean
appearing; seemed like it was pretty sooty.

The ET camera is mounted on the LOX feedline fairing. On an HD source,
it is quite evident that it is the feedline vibrating and not the rest
of the tank. With a poorer quality video source, the fisheye lens effect
makes it difficult to discern where the feedline leaves off and the rest
of the tank begins.

I don't have a documented source for that, but I know from multiple
sources that it is true.

The ET-Cam is HD? I've never seen any images from it remotely close to
HD. It looks very, very SD to me.

Okay, Jorge! Quit hogging the HD videos from the ET-Cam! We want to
see them! :-)
