I was watching the video at liftoff, and I saw
the roll. I'm not sure what to make of that.
Most of the rocket mass is fuel -- some 95%, I
believe; and the body of the rocket can rotate
on its long axis without rotating the fuel.
I'm thinking about that because those axial
rolls started sharply, were fast, and stopped
sharply, which implied a lot of force applied
from somewhere. Might it be, the force of the
axial roll, damaged the 2nd stage release
system, which then failed? If I were designing
such a system, where weight is *everything,* I
doubt I'd make it strong vs axial roll forces.
I notice Musk says he's brought in a "large"
investor. I don't like to hear that, for now
Musk no longer entirely owns his company. Who
are the new people and what's their track
record? ??

As I say, you have the advantage, being able to see the video, but from the
description I immediately thought of an uneven release putting the motion
into the stack and then its too late.

That's interesting...Rutan's Scaled Composites got bought out by
Northrop Grumman recently.
(They owned 40% of the stock before the buy out.)
Scaled Composites just issued a update on the SpaceShipTwo nitrous
oxide explosion BTW:

I can't guess what to expect, but I think I may not
like it. I heard Musk about his work about two years
ago, at which time, he seemed to believe what he was
doing would completely upset the pricing applecart.
Which I expect, will thereby provoke strong resistance
from those whose money is there. $10K/lb to orbit:
that is a lot of money and *somebody gets it*. Now
comes Musk saying, $1K/lb to orbit and we'll be
bringing it down. How do you think the $10K/lb people
feel? So I suspect there is some very rough stuff
behind the scenes here and we aren't hearing about
it. If someone has enough money to buy Musk and put
him out of business, that's the "nice" way to do it,
but as these stories come along, I've my eye out for
deliberate, very indirect but effective, *sabotage.*
On this topic, whatever happened to that SSTO that
looked so good recently, whose preliminary tests were
so encouraging? I.e., what *really* happened? ??
For a look at some of this stuff, see "The Return,"
by Buzz Aldrin and John Barnes. Paperback, 2000.
Get that into your head and let it work arond a
little. If you have any industrial experience, that
will come in to it too.
