It helps keep the sandworm population down to a bare minumum, and if you think twenty thumpers will call a bunch of worms, just watch what happens when someone fires off an SRB or two from Canaveral!

Surprisingly, urban explorers have not found as much water inside the silo as one might expect. Certainly there is water at the lowest level, but it's not like the silo is completely full of water. The engineers must have done a good job making the thing relatively water tight. If it had been used operationally, I'm sure an appropriately sized sump pump would have sufficed to keep the silo dry. Jeff Well, part of the problem isn't so much water intrusion as much as creating a "raft". As long as you anchor the silo or somehow make it weigh enough, it shouldn't float to the surface. -- Greg D.

Encyclopedia Astronautica says, "There was considerable concern about building such a huge facility below the water table, but the 50 m depth proved no problem for a competent caisson contractor."

Encyclopedia Astronautica says, "There was considerable concern about building such a huge facility below the water table, but the 50 m depth proved no problem for a competent caisson contractor." The issue I see is how do keep it from popping out of the ground in rainy season. I know! Fire off a test every so often to drive it back down. I'm still trying to grok how the "starter" worked. They talked about it being tethered on cables and ?going around in circles?

Turns out a friend has been there. He worked for a guy who had a contract to make some sounding rockets for NASA. They visited the site as a possible manufacturing location. The only use being made of it at the time was the cops had a target range in one building. The rockets they made were solid fuel, with a nitrous oxide tank on top. They topped it off as it boiled until just before ignition. I got to sit in the control room at Wallops Island during one launch. -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |

There is quite a bit of info about this on the Internet. As usual, astronautix.com has a good summary: AJ-260-2 http://www.astronautix.com/engines/aj2602.htm NASA Technical server has a very good report: FINAL REPORT DETERMINATION OF PROCESSING AND TEST FACILITY REQUIREMENTS FOR LARGE SOLID ROCKET MOTORS VOLUME I: TASKJ -FACILITY MODIFICATION FOR FULL-LENGTH 260-IN.-DIA MOTOR PROCESSING AND TEST http://ntrs.nasa.gov/archive/nasa/ca...v/19700027475_ 1970027475.pdf Also, there are several websites showing pictures of the site taken by "urban explorers" (or whatever they like to call themselves these days).
