Bringing this over - as the old thread was playing up:

How was that airlock moved from the Internal to External configuration?

Even if it came apart, that seems to be a very unwieldy piece of metal to pass through the crew cabin pressure hull!

We all know how noisey a launch is. How do the astronauts get protected by that incredible noise of the SRBs during ascent when they are just a few hundred feet above those beasts?

The orbiter structural protects them and they are wearing helmets.

It did come apart in pieces and they went out thru the payload bay via the hatch area.  It was design to do this.

It also helps that the sound is travelling away from them.

On some of the in-cockpit mission tapes I have, the ambient cockpit sounds can be heard quite well. It gets pretty noisy in the transonic region and around Max Q...you really hear the wind out side the cockpit...kind of a howling/whistling sound, and the instrument panels seem to rattle rather loudly. After SRB sep it is very quiet.

So yes the crew is in front of the noise and they are in a sealed cabin with communication caps ("Snoopy" cap) and Helmets on, but it does get pretty noisy in the cockpit.

Unfortunately my only reference is the SMS (shuttle mission simulator) and what crew members have told me. The SMS is semi-realistic with a little "shake, rattle, and roll" and some simulated noise. Crew members say that the real thing is no comparison...

Here's a question regarding the HRSI tiles on the forward part of the OMS pods. Why were they added? On early flights with the orbiters they lacked them, but later they were added. Any specific reason whey they were added?

Does a shuttle launch leave behind any kind of a long-lasting smell in the pad area and if so does that smell even reach the press site and viewing areas?

Turbulent airflow off the chines was striking the pods directly (see STS-1) and was hotter than predicted.  It also shredded the AFRSI on STS-6.  Also they were taking some debris hits.  So the thicker HSRI tiles were added.

Depends on winds, but there is a smell

Thanks, I suspected it was something like this.

During 41B, ice formed on the dump lines and during entry that ice broke off and hit the left OMS pod. They had to replace that pod with a pod from OV-103. To prevent more damage they changed the tiles in the area. To preserve geometry they also changed the tiles on the right OMS pod.

Thanks to mkirk for the words on the camera lines!
GLS is go for main engine start!

I've heard of them changing tiles on the pad. Is that harder to do than in the OPF?

It really depends on the location of the tiles in question.  The OPF is by far the best place for tile work since you have the right kind of access and can control the environment easier.  Pad work is doable but not desireable.

They have used scoffolding and temp platforms to do tile work at the pad.  But if it is on the belly between ET, then no access

Zoomer asks: " have searched and searched and found no question like this. On the NASA mission pages they show the SSMEs used (like SN-2001, etc) Is there a place that shows the different versions of the engines?"

I'd suggest searching with some of the different types -- Phase II, Block I, Block IIA...for example, I found this in a Google search:

OK, my submission for "dumbest question of the year" award...

Rather than retiring all the shuttles in 2010, would it be possible to leave one permanently docked to the ISS as a lifeboat?

The only dumb question is the one that's not asked.

Orbiters can't survive in space for too long. Even if you took away the power requirements, they'd get very ill very fast with the whole enviorment of space.
