Both ends of the spectrum within a few posts. Read the details!
It is not launch fever, it is not being ignored.
Yet, it is not a non issue

Where I have I heard that logic before?
Many earlier shuttles experienced O-ring erosion and never had any problems
How are you able to compare the hose kink with O-ring erosion? Is there something I'm missing?

The general attitude "we flew with it before therefore it is ok to keep flying the same way"

I don't think that attitude is present in this case either, but you certainly are entitled to that opinion. I'm not sure how you got it - but it's probably worthy of a different thread if you want to point out how that's at play :cool:

Updates:
PLBD closure with the pole/stick methord classed as Sunday, though we have engineers who think it'll be Momday - we'll see.
The tech with the pole is not Boeing, but USA and KSC based. He went to Huntington Beach (Boeing, California) to practise the methord (as seen in the image used in the latest article on the news site).
New article will be later tonight now with a full, expansive overview, based on that wonderful presentation from yesterday.

This is the point I was trying to make, guess I just was doing it the hard way.
They have looked, and continue to look, at the problem. It is not being ignored, but is starting to be understood well enough that it is becoming clear that even though it is not as designed, it is just fine--just like the worn windshield wiper.
EDIT: I don't think the situation is comparable at all with the O-rings. Instead of looking at it and saying 'we've seen little tongues of flame but nothing has happened so it's ok', they are taking a solid engineering approach and making sure there isn't something to bite them.
In the end, making an informed decision that even though there is an acknowledged issue, it is not a problem that has a realistic likelihood of causing a problem. And by saying that, I mean that the risk of flying with this issue is less than risks accepted as part of flying the shuttle (or any other spacecraft) on any day.

No, that is why they are fixing it

We may just be tossing semantics back and forth. In my mind they aren't fixing it, they are mitigating the kink for launch. But from what I have read here, based on the Discovery hose the kink will come back when the doors are cycled again.
When they fix it, they will replace the hose without one with a kink in the steel braid. We probably have the same idea, just using different words...

I believe it is a non-issue. Once the doors are closed for landing, the radiators are not used. Even if the kink was bad enough to restrict flow at that point, the system is isolated and poses no risk or problem.
.
But the RAD system IS used after door closure

http://www.nasaspaceflight.com/content/?cid=5346Based on the superb 52 page presentation on L2. Included some screenshot images into the article.
Remember, if you're on another forum, URL ACCREDIT US. Don't wait for someone to say "where are you getting this info from?" before saying NSF or something vague, in passing. And don't copy posts or info from this site without saying where you got it from with a URL. Some "space sim" sites posters are acting like it's their own info, when it's literally copied and pasted from this site!
You are being noticed by regulars to both sites and they are letting me know. I will ban you.

Anyone know where they are hiding the TV Schedule for STs-122 on that new NASA Web site..you know, the Excel spreadsheet?
Or hasn't it been released yet?

A lot of the second level or lower level links haven't changed; this is probably the same:
http://www.nasa.gov/multimedia/nasatv/mission_schedule.html(The direct PDF link hasn't changed as I pulled Rev. 0 this morning with the same URL.)

Thanks psloss. Should have used my Favorites link.
I would suggest bookmarking Harwood's:
http://www.cbsnews.com/network/news/space/currentglance.html#TVSKEDAnd veering more off-topic, I Googled for pages linking to that NASA.gov link and found an interesting code project. (Never heard of it before.) Not sure if this has already been posted in the forums or not; anyway, for those MS Outlook users who are adventurous:
http://www.codeplex.com/NasaStsTvSchedule/The NASA Space Shuttle TV Schedule Transfer to Outlook Calendar provides an easy method for you to include NASA's Space Shuttle mission schedules in your Outlook Calendar.
It reads the NASA TV Schedule published by NASA on their web site, in an Excel spreadsheet, for Space Shuttle missions. It can also transfer the TV schedule of events to your Outlook Calendar as Appointment Items.

A per live coverage on L2...Around 8pm tonight. (updating key points into the article on site).
