If you're truly an "investigator", why don't you spend less time on idiotic posts like this one and answer Scott Hedrick's questions about your "team mates", rk's and Michael Gardner's questions and comments regarding your statement about the electrical loads, currents, impedances and cabling in the spacecraft, my comments about the LiOH canister testing you allege should have occurred, or Daniel's comments regarding the test procedures?

Could we in future move substantive comments out of the troll threads
into appropriately named threads of their own? It's better netiquette and hopefully wil make the group read 'cleaner' since it allows for the killfiling of individuals rather than threads. (I'm know, I'm guilty too... But I'm taking the pledge.) D. -- Touch-twice life. Eat. Drink. Laugh.

"LaDonna Wyss" wrote in message OM, you are such a windbag. Did I say the hypergolics were on board? I said they fired the thrusters, and they did fire the thrusters. If you people are not going to take the time to learn what happened out there that day, how can you pretend to debate? Um, I thought that "fired the thrusters" meant "issued the command that caused the thrusters to fire, causing the thrusters to operate in such a manner as to cause thrust." It does mean exactly that when they are connected correctly. The you can operate them dry or wet. Dry = no propellants. Wet = propellants loaded. NASA has a silly habit. They label such things "loaded". They do this in many different ways so that unsuspecting workers don't get killed. Where the hell is Kim Keller when we need him? Daniel

Actually, I *think* that what scott and his followers are referring to is a Service Module RCS hot-fire. IIRC, even on Block I capsules, they never did a hot fire on the CM's RCS until fairly shortly before separating from the SM. snip Bottom Line: The RCS fuel is nasty stuff, and there's no way in ****ing hell that it would have been tested on the ground as LaDip**** or "scott" claims it was. In fact, the tanks weren't even fueled up that far in advance of the launch, which was still, IIRC, almost a month away. Even if they were, doing a test firing like that would have a) been hazardous if not fatal to the Pad Crew, and b) would have contaminated at best the entire White Room and adjacent work areas. Remember, though, that what was later called the "wet CDDT" (the full dress rehearsal of the countdown, including propellant loading, etc.) had just been completed on AS-204 a few days prior to the fatal Plugs- Out Test. (The Schirra crew was inside CSM 012 for portions of that earlier test.) If I'm not mistaken, the wet CDDT included the fueling of all the booster and spacecraft systems (including the CSM's cryogenics, the SPS propellants and the RCS propellants). I know that, once you loaded the hydrazine/nitrogen tetroxide fuels, you had a finite remaining lifetime of the propulsion systems, since the fuels were corrosive to the seals. What I'm not at all certain of is whether or not the SPS and RCS tanks were emptied and re-filled between the CDDT and the actual launch. The cryogenics were definitely emptied and later refilled -- does anyone have a definitive answer for the SPS and RCS tanks? The point is that the RCS tanks were indeed filled for the earlier wet CDDT, and that they *may* have still been filled during the Plugs-Out Test. But since they weren't going to retract the White Room or the access platforms for the Plugs-Out Test, but still wanted to exercise the procedures for the hot fire test, the RCS was disabled and the hand controllers wired into an RCS response simulator for the Plugs-Out Test. Since the S-11 switch and the hand controllers (among other things) all fed into the wiring that was redirected to the response simulator, there is *absolutely* no way that any manipulation of them could *possibly* have caused any response of any kind back in the SM.
