Not to mention removing it reduced the weight, and increased payload capabilities.

It wasn't paint. It was a Fire Retardant Latex(FRL). The FRL was to protect the ET from aerodynamic heating during ascent. After STS-2 NASA decided to stop using the FRL as the regular SOFI provided adequate protection.
My bad. But was I correct on the weight? About 600 lbs?

IT HURTS THE EYES...all that white! J/K, but yeah, it was fluorescent, and a bit tacky...
I'd take the usual gold...orange...caramel...rust ANY DAY over that nasty white.
I concur. It just looks very plain and...sterile, being all white. The rust color gives it some character at least. Just my humble opinion.
Maybe a red, white and blue scheme for the very last flight as a show of patriotism?
Just kidding.

Does anyone have a good idea as to when the Flight Readiness Review might be? I'm headed down whenever this flies and I'm trying to do a little planning. Thanks in advance!

As per L2, they are working off Delta FRR and LRRs right now, and it looks like the FRR will be about the 24th if I read it correctly.

Martin FL - Thanks for the information and for the quickness of your reply. I have seats at the Saturn V Center for 117 and I'm thinking of waiting to make my airline reservations until the FRR. I bought tickets for the March attempt and wound up eating a BIG change fee! Thanks again...

Just remember that it took over 600 lbs. of paint to make that sucker white Also, talk about a debris hazard!
Do you have any info that would say the paint would be a debris hazard? My own feeling would be that it would have acted like a skin to keep pieces from flying off.

There's one good source: The STS-1 Technical Debriefing of Young and Crippen. In there Crippen mentions that some foam from the ET impacted the windows and actually got stuck there for the remainder of the flight!
I'll see if I can't dig up some post-sep photos of the ET.

In the STS-1 Orbiter Final Mission Report (JSC-17378), p. 85, it was noted that Columbia sustained damage from debris strikes during STS-1 and that more than 300 tiles had to be replaced. This report was referenced by the CAIB report on p. 122.
There is no evidence the latex acted as a skin to keep pieces from flying off. The forces involved in "popcorning" foam are too strong for that - if anything, when popcorning occurred, the latex would have caused adjacent foam to be pulled off with the popcorning piece, increasing the size of the debris.

... and the pencil point area is the final area for repair, isn't it, and now just needs dressing off. So rollout is looming....

Look at the classic photo of STS-1 waiting at the pad. You can see an area encapsulated by a debris net strapped to the tank. This is where an area of foam roughly the size of a filing cabinet came off in one integrated piece.
The current philosophy we work to in the foam world is that since we know foam shedding in flight is unavoidable, its best to make sure it comes off in small pieces that do not present a hazard to the rest of the vehicle. Having a 'skin' that has the potential to keep very large pieces of foam together while shedding could lead to a really bad day.
Edit: Sorry, I posted before I noticed you got an answer to your question. My apologies.

Don't think so, although there is a review on the 11th.
Having said that, the tank is almost finished with, so there might be an opportunity.

An early rollout would be cool, plus it would give a few more contingency days. I am just glad that all the repairs were successful and if they need a few extra days to finish them, fine by me. Just looking forward to Atlanits being back at the pad.

The exact launch time really isn't known until they're in the last parts countdown. The ISS orbit changes with reboosts and such and changes the times up a bit.
