CardMan did you follow the news about the foam shedding AT ALL?

I watched it live as it happened. I have also been keeping up with
what the stupid scare story seeking tabloid media have been saying.

The foam
that broke off could have easily punctured the wing just like it had with
Columbia if it had come off just a couple seconds sooner.

That would be a snowballs chance in hell situation.

To begin with then the foam that got Columbia was certainly both quite
larger and most importantly it came off in the low Earth atmosphere,
when Columbia was ploughing though it a quite some speed.

The foam piece wasn't that much larger and could have damaged a wing panel
irrepairably had it come off with greater speed.


In the case of Discovery this foam only came off due to what appears
to be direct SRB separation. So it did not, and would not, have come
off when it could have posed a danger.

AFAIK this link hasn't been made nor has it been proven. It might well have
come off earlier, there's no telling at this time.


Indeed it seems like the case that Discovery traveled through this
lower atmosphere danger zone with no foam loss at all. That should be
a first for any Shuttle launch.

Certainly this foam loss is undesirable, but this tiny risk is not
reason to ground all their Shuttles for.

Since Discovery was well up into the high atmosphere at this point
then that it why this foam slowly drifted away. As I said before I am
sure that you could head butt that foam without knocking your brains
out. So had it hit Discovery, then it simply would have bounced off.

What is more is that since this foam came off due to the SRB
separation, then so did the passing SRB create a pressure void that
this foam was sucked into. And well away from Discovery.

So based upon the cause, and resulting affect of this foam loss, then
I would declare their previous foam problem completely fixed.

Luckily this time around we would have known about it

Yes, NASA does not do too well with foresight.

but it would at the very leas it would
have meant the loss of another Shuttle (repairing it in orbit would be
virtually impossible)

Oddly enough, NASA this very trip, is testing their new repair
procedures. Although I really cannot see the point of repairing the
chip marks on the tiles.

The repairs their doing are bull**** and you know it. They're trying to fix
small dents in tiles that don't need fixing just to satisfy the American
public and the politicians. There's no way that they can repair a carbon
panel on the wing, and they've said to publicly.
