Oh, mean, cruel; go ahead and gloat, just keep it descriptive! ;-D Did you see the latest mention of the SR in the Wash. Post? Not to dredge up the old 'cost' per hour, but they had their quote of $39K/hr. Again, I'm not challenging, etc., your quote of $25K, just another data point. They quote Eugene Carrol of the "Washington-based Center for Defense Information", and Robert Behler, "Commander of Edwards AFB, and a former SR-71 pilot", AP byline. Interestingly, it adds that the sealant had been declared a carcinogen, and that, fortunately the AF had a lifetime supply made up prior to this that they can use, thus not violating any laws by making more. `"That was our big showstopper" Zimmerman said.' ("Capt. M. Zimmerman, [who] managed the restoration program from Wright-Pat.") This is prob. old news to most, but some may not have seen the article, from the Dec 18th issue. regards, ________ BaDge ------------------------------ From: "I am the NRA."

SHARP uses nurning methane to compress hydrogen, which (once pressure is up) ruptures a disk and "air guns" what ever is in the tube down range. Eventual possibilities include a mass launcher (G levels too high for humans) for orbital insertion.... Hydrogen is strictly a working ~fluid~, does not burn (except incidentally....). regards dwp ------------------------------ End of Skunk Works Digest V5 #587 ********************************* To subscribe to skunk-works-digest, send the command: subscribe skunk-works-digest in the body of a message to "majordomo@mail.orst.edu".
