I am well aware that Challenger was caused by a leak of hot gases between two segments of the booster. My understanding from the time was that they did it that way (multiple booster segments instead of one massive piece) was because of curing issues.
Technically, both Challenger and Columbia were not in space. Challenger was well within the atmosphere during liftoff, and Columbia was about 40 miles (about 65km) up, well below the 100km mark.
However, the Russians did have 3 deaths in space, on one of the Soyuz/Salyut missions (my apologies to any Russians, I don't remember the specific mission number). Komarov on Soyuz 1 was probably not an in-space death as well -- his chute tangled, and I believe he died on impact, which is definitely not an in-space death.
So out of 18 known in-flight deaths (and I am not counting Apollo 1, that wasn't in-flight), only three were in space.
If they ARE going to be used, move the construction to a sea port so they can be shipped intact and don't have to be built in stages.
IIRC, from the time of the Challenger disaster (when we all learned about how the SRB's worked), and partially from a book on the original Minuteman (first solid ICBM), the issue is really the curing of the propellant, and doing it in stages makes the curing easier and more reliable.

Rocketdyne was owned by Boeing. Boeing just sold the Rocketdyne facility to United Technologies (which may be P&W for all I know).
There was a lot of angst about this sale. Me, as a local spacebuff, I just want to know what's going to happen to the F-1 engine sitting out front of the facility.
As I said, we realize that there's not a damn thing we can do about malicious intent.
What the boss is concerned with is more along the lines of: "we use USB sticks for transferring data all over the place, including non-company machines (during demos, etc...). Sometimes a USB stick may be placed on a machine connected to a non-company network (e.g. a laptop). We want to avoid accidental disclosure in such cases."
Personally, I think the founder is a bit paranoid, but our company is an R&D company, and that info is our crown jewels, so it's a bit understandable.
Our current policy is to treat them as any other removable media.
Actually, that wasn't quite true. If you used the kernel sockets layer (ksl), then yeah, you did need to relink. If you used the old-fashioned user mode IP configuration, you didn't.
Read Arthur C. Clarke's Earthlight. There's a lovely section where the entire crew of one spaceship has to "breathe vacuum" in an emergency escape to a second ship.

In Stephen Baxter's Voyage, he had NASA do something similar... they strapped 4 SRBs onto a Saturn V to create the V-B.
Reusing existing hardware is a wonderful idea, while new technology is developed. And it gets us away from the horrendous side-mount.
My only question is: Is the Shuttle ET strong enough to hold 100 tons on top?
Makes it kind of useless for handing somebody a 100MB PPT file (and yes, we've thrown those around).
Yep, but it was still side-mount.
Question on the new designs (from TFA). Is a Shuttle Tank sturdy enough to carry 100tons top mounted?

1. You only have 95% of your comments
2. I'd argue that your Item 1 is part of Item 4., assuming the function block comments are accurate.
But it doesn't seem to help when I use it on it.slashdot.org... the colors are still weird looking, no matter how many times I click that button!
Your comment gives new meaing to the phrase, "Hey, baby! Nice rack!"
The spec for declassification is DOD-5220.22M
Happened on the last one ("How many computers fixed...") as well.
All 95 grievances?
I'll create my own casino! With blackjack! And hookers! On second thought, forget the blackjack!
Seems to me that they closed it (Win2KSP4, IE6SP1). It installed the damn GA ActiveX no matther when I tried that javascript.
Who's chipping in for Lance Bass' [one-way] ticket?
Apollo 12 was struck by lightning, for $DIETY's sake!
It wasn't a quip. The guy was staring at his telemetering console, not looking out the window.
Quit conflating "free as in beer" and "free as in speech".
ReiserFS was an option at least as far back as MDK 8.1.
Anybody have any links to the TankCam of the SRB and/or ET sep?

Only if you wear a bro with your puffy shirt.
