Re: Foam still a key concern for shuttle launch

Firstly it would be helpful to correlate flight testing with the events
that led to the sts-107 tragedy, and not just attempt to control the
conditions for foam liberation during ascent. In my researching the
sts-107 tragedy, I have noticed just as the caib and previously many
other independent assements, the slippage in safety, which been noted
as contributing factors to sts-107, and sts-51l. The concept of
controlling conditions for which the atmospheres unpredictable behavior
dominates in the lower atmosphere is attempting to control mother
nature, and murphys law will win if tested. So I do not believe
stating "we think we have done that" in reference to "containg
and controlling" what the caib determined was the cause of the
sts-107 tragedy, foam/ice liberation is demonstrating any increase in
wisdom from past tragedies. Therfore we must increase our
understanding of the caibs determined cause for the sts-107 tragedy by
flight testing, and correlation, then update our risk assesemt process.

My motivation here is strictly to improve the space program for our
flight crews, not ground it, and not seek infinite funding, but a
balance that has not yet been achieved between program expectations and
financial support. I have shown and provided in the space shuttle
group my findings and supporting evidence for the necessity to make a
full orbiter program quantitative risk assessment. This would provide
nasa engineers/managers and the administrator himself with the best
available tools for ensuring the space shuttle safely completes it
operational stated goal of space station construction, and retirement
in compliance with human space flight regulations.

This is an expensive endeavor, as all of the technical drawings that
comprise the orbiters systems will need to be digitized and
converted/cleaned up in a cad file. Nasas current qra utilizes cad
drawings as input, so therefore prioritization will need to be given to
the orbiters various systems for input from raw drawings. The benefits
of an updated qra will directly provide nasa decision makers with the
best possible information, and provide a training basis for the next
generation of nasa managers. Additional benefits will come as the
designs of the shuttles systems can be historically cataloged, and
utilized for the next generation winged space vehicle. Understanding
the benfits for an updated qra, helps put in perspective the drawback
or dollars required for a shuttle program qra, and as I pointed out
before investments in upgrades vs risk reduction do not reflect the
production of the space shuttle, and that is space station
construction.

your own writings here on this thread as moronic. Secondly you have
been outwitted by me on this and other threads on the topic, that is
why you have had to resort to insults and ad hominems demonstrating
your lack of critical writing skill, much less youre understnding of
logic thinking.
Now once again, you have not shown in any way shape or form any kind of
supporting evidence that testing has "exceeded the point of
diminishing returns" that represents reality. Nor have you
demonstrated how nasa is attempting to "fix an unfixable problem. Now
you may want to shield yourself from reality by hiding behind quotes,
but once again your economic model of marginal returns on rtf or safety
upgrades neglects the space shuttles output, that is the space station
construction. So if you would care to retract you statement, or
support it either way, but at least show attempt to take repsonsiblity
for your un-supported, non-correlated, non-validated opinion.

Okay Tom, Rand's rudeness aside, what do you propose NASA do WRT the
foam tile issue right now? I'm just curious what your course of action
would be.

You have stated nasa should "stop trying to fix an unfixable problem",
and that "they've exceeded the point of diminishing returns" without
factual citation correlation or validation in support of you're
opinions.

Look, idiot. I already posted a quote from an interview with the NASA
administrator in which he says the same thing. Go argue with him.
