A friend of mine, r. stoert, invited me to test his preferred world: the Internet: So: Is there anyone out there who can answer me a couple of questions on helicopters, I. Sikorsky, etc? I am mostly interested in both historical and strange informations...! I need the info for an over-all work on the Psychotopologic History of the Helikopter. 1) -- Which was the first helicoter to see military action on the side of the Alliies in WWII. -- which Model, when build, where/when in service, unit? I believe it was some Sikorsky model, need confirm. -- There is a Hollywood movie feat. YulBrunner/RichardBurton (a.o.) about aNazi Fortress on Alpen-mountain-top, allied commando escapes with Heli in this flic. -- Name of the movie? anything heard about reference to reality a/o fictional operations linked to helicopters during the early years. General Sikorsky Information. 2) Howard Hughes Aircraft Industries -- when started heli-development a/o production ? -- which where the models? -- when did it happen? -- general information about the early time, evt. Gossip/Info about Howard the Person &his possible possesions/myth-data/nut-talk with the subject helicopter. 3) ANYTHING on Soviet/Russian helicopter engineering in the beginning & medium pasttime-range, like names of constructionists, vita, years, models, illustrations, photo. Iso far know about Professor Mil & comrades & one Komitee called ZAGI, these guys builded 3 thre prototypes between 1930 - 35 , or so says the propaganda. 4) Material on Helikopters which appears strange/rare/interesting WHATSOEVER. 5) Please, don't hesitate to name ftp- or gopher-sites, libraries, etc. Thanx in advance.

Webb which he's given me permission to quote: [begin Webb message] There was a front-page article in yesterday's (Sunday) NY Times about an upcoming auction at Sotheby's of Soviet space program memorabilia. To be auctioned off are such items as turn-of-the- century monographs of Konstantin E. Tsiolokovsky, the slide rule of Sergei P. Korolyov, lunar fragments, an elaborate never-used space suit, and more. Some of the humbler items have stories behind them, for instance: "A badly frayed space glove turns out, in the telling, to have been critical for an astronaut who spent seven desperate hours in a space walk, clawing at a damaged hatch that threatened doom. An innocuous packet of nuts and bolts from one of the earliest flights was nervously collected by an astronaut startled to find pieces of his spaceship coming loose, just like parts of a badly made Soviet automobile, and floating about." One final anecdote: "The tales sound as potentially priceless as the various artifacts offered by Col Aleksei Leonov, the first human to walk in space. He returned to earth badly, landing far off course in the Urals during a three-day blizzard. He managed to build a fire outside the capsule with some tree scraps, only to be chased back inside his snowbound space ship by a Russian bear... Colonel Leonov thereafter ordered a special combined flare-and-shotgun designed to deal with bears." : Dennis Webb : : : Hoffman-II, Alexandria VA : "Quot homines, : : (703) 325-6582 : tot sententiae." : : webbd@hoffman-emh1.army.mil : : [end Webb message] More details from the 8 August *Times* article: Auction is 11 December. Stuff will be on display at Sotheby's for a week preceding the auction. (We may hope that some Usenet correspondent will report on this...) The spacesuit is one designed for a Moon landing. Most of this stuff seems to come from the personal collections of cosmonauts looking for cash.

It isn't, though there seems to be a minority that regards it as such. A "physics book" written by the orthodox probably wouldn't list this as the earliest definite evidence of particles with fractional charges, though it might mention it as a curious and not entirely explained result. There is a big difference between finding quarks and finding free quarks. Today the evidence for quarks is fairly solid and pretty universally accepted in the particle physics community. The evidence for free quarks is *not* universally accepted. Of course, that doesn't mean Millikan didn't see them, but it would be misleading to claim that it's common knowledge he did. The apparent nonexistence of free quarks was initially considered a stumbling block for the quark model of hadrons, and in that era free quarks were searched for extensively. Eventually quantum chromodynamics, with its self-coupled gluons, gained popularity as a dynamical theory of how the quarks interacted with each other. The computational evidence seems at the moment to favor the idea that QCD (1) is correct (for instance, it seems to predict hadron masses correctly) and (2) confines quarks to the interior of hadrons, by means of a tremendous attractive force that does not diminish with distance. The discovery of fractional charges in Millikan's data would *not* be dramatic confirmation of present ideas of physics; it would, rather, be a dramatic surprise in contradiction to current theory. If the fractional charges were quarks of the usual variety, the oil drops would possess a net color charge-- and they, or the free quarks on them, would be subject to forces far in excess of the electrical ones exerted by the Millikan apparatus. -- Matt 01234567 <-- Indent-o-Meter (mod 8) McIrvin ^ Void where prohibited by your editor. ------------------------------ Date: Mon, 9 Aug 1993 19:54:07 GMT From: fred j mccall 575-3539 Subject: Cold Fussion, NOT! just not been proven real well!?

Other astronauts in the "down" bunk have reported higher sleep disturbance rates, and there's just enough of a statistical sample for the results to be significant. So there will be no "down" bunks on new spacecraft, Freedom included. [For those of you who aren't familiar with the shuttle's internal layout, it has one of the sleep bunks oriented so that it's essentially on a local "roof" relative to spacecraft "down", which is down when the shuttle is sitting on the ground on its landing gear.

If you follow the masses of launched spacecraft, they VERY closely track the max mass which that launcher variant was capable of launching for that mission.

[...] If you're regularly launching midsize missions (example: Regular service by Soyuz or Progress to Mir...) you just throw your left-handed metric 8.65mm spanner in the next flight and forget it. Or beg, borrow, or steal a secondary payload spot on the next possible vehicle if it's going to orbit, not a station. Missions where you suddenly need an odd-sized item are rare because of the time scales invovled in space activities. Most launches are pretty big, because sattelites are pretty big, and they don't have any opportunity for going back and tweaking a one-pount item. Any situation where needing odd-sized items at irregular intervals is likely to come up, you have lightsat launchers or regularly scheduled larger launchers with some small discretionary payload available. You design your vehicle to take up the whole possible payload mass, using "spare" fuel (i.e. not mission critical) as the margin mass or something similar. As things develop, you solidify the masses more, can tell how much extra fuel you can actually bring, etc. If you're running over, you cut and cut and often have fits about problems, but if you're running low you can always find something to take up the extra space or mass ;-) that's easssy..... Most vehicles, by flight time, are a whole lot closer than 95% of the max flight weight allowable. -george william herbert Retro Aerospace ------------------------------ Date: 9 Aug 93 23:31:55 GMT From: Paul Dietz Subject: Low Tech Alternatives, Info Post it here! Newsgroups: sci.space About cost/lb, with half-full launchers... The TRW/Boeing cost optimized launcher study of the late 1960s concluded that it would be cheaper to build (for the projected launch rate) a 100,000 lb capacity launcher and sometimes launch it half empty, instead of developing more than one launcher to more closely match payload size -- and this for a vehicle that had a development cost of a bit over $2 B (1993 dollars). Of course, once the market gets big enough, one can amortize the development cost of more nearly optimally sized launchers. Paul F.

What people are guessing about is the occurrence of a possible Perseid *storm*, which will be much more worth seeing. Meteor showers are exciting only to dedicated enthusiasts. Meteor storms can be awesome. Last I heard, this year was still the best possibility for a storm. Earth will be in an unusually good position; if the Perseids are going to storm, this is the year for it. There is reason to suspect they might. The *most* *probable* time for a storm is 0100 UT on the 12th, which is 2100 (9PM for the innumerate :-)) on the 11th EDT. This is not good for North American observers, even on the East Coast -- the sky won't be very dark yet. The surge of activity last year which produced the storm prediction for this year was fairly short. On the other hand, that time is only an informed guess. It might storm then. It might storm four hours earlier, or four hours later. It might even storm all night, although that's rather unlikely. The gung-ho meteor observers will be up all night just in case. If you aren't that dedicated, plan to spend the evening of the 11th, say from sunset to your bedtime :-), in the darkest outdoor area you can find. Note: Wed 11th, not Thurs 12th!
