Is there a contingency if the vertical stabilizer separates from the orbiter during launch?That's a question along the lines of other very remote ascent 'what if???'s Like...- what if all the elevons fell off?- what if the payload doors suddenly opened?- what if one or two engines fell off?- what if the commander had a heart attack during ascent?- etc., etc....In other words, it's an incredibly improbable event; so much so that's it's almost silly to ask those types of questions, IMO.

They did another episode about the ISS leaking oxygen while the Shuttle fleet was grounded after the Columbia disaster. They decided to fix the leak using a top secret military space shuttle, but only after its existence was leaked from within the administration.
I have a question: where in the space shuttle is an APU power?

It would be behind that panel. There are three, but I couldn't tell you how they are oriented within that section of the Orbiter. Hope that answers your question.
What is the size of the parachute brake Orbiter weighs and how much? And the same question about parachutes SRB?
The APU's and the sound that they make (chuf, chuf) when operating have been discussed previously in this or one of the other three Shuttle QandA threads. My question has to do with what might be the visible exhaust from these or the water spray boilers that serve to cool the APUs' lube oil and the hydraulic system's fluid. On one of the orbiter landings, after wheels stop, but prior to APU shutdown, what looked like steam pulsed out of the top/aft of the orbiter. Is this APU (expended hypergol) exhaust, or steam venting from the water spray boilers? As you can see from the attached the vents for each are located fairly close to one another, on either side of the orbiter's tail. I'm guessing the latter, because I'd hate to think about the impact/toxicity of hypergol exhaust.
