Not risking astronauts lives how about ascent abort? Bob Haller 06-22-2006

So shuttle lifts off normally foam loss noted about the time a ascent
abort is called. Shuttle for whatever reason must reenter immediately.
Perhaps a low fuel sensor failure? were flying with that problem still
questionable.

so upon reentry we lose another vehicle and crew.

So how does griffin justify flying with contiuning foam loss?

This is off the main topic of your post, but didn't they find that a
subcontractor had made a batch of a part that wasn't up to spec and
that was the cause. Seems like I read that a few weeks back on a
science/technology/space site and never heard about it again.

I do not think losing foam at some stage is the problem here, its the impact
of large pieces, possibly with ice as well, which clobber delicate parts of
the orbiter.

Tiles seem reasonably tolerant, but the rcc seems to be the problem mainly
occupying the mind of those involved.

Nasa didnt appear confident of the sensor swap and wanted a load fuel
test. But decided not too since that may lead to more foam loss......

so how confident are they? The sensors could cause a abort....

That's easy. He justifies it because he believes that the risk of loss
of life and vehicle is within acceptable limits. That's a decision
which he takes being the Administrator.

If you were taking the decision you would probably never get outside
your front door. But he has slightly more courage.
