I don't have figures handy for the F-15 airframe, but a historical note may give a slightly clearer picture on "Military safety margins" (if my memory isn't flawed). The rated plus-g for the F-4 was something like 5 g. Pilots in Southeast Asia almost routinely did 8-g manuevers when avoiding flak, etc., because going outside the envelope was better than being shot down. I don't know of any aircraft that went down from structural failure, and I would expect that if that had happened it would have been widely publicized in the anti-war press of the day. I would suspect that you would have more serious problems than g-induced structural damage if you did 10-g manuevers in an F-15, since you have almost assuredly exceeded the g-tolerance of the wetware. In point of fact, there have (apparently) been instances of near-instantaneous GLoC which resulted in loss of aircraft in F-16s doing 9-g pull-ups. Structural damage from g loading ceased to be much of a problem if the aircraft impacts dirt. I also assume we're not talking about jolt, but about sustained manuever, since I think planes coming off a cat take higher jolt than 10 g. -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Ames Dryden ------------------------------------------------------------------------------ Fred.McCall@dseg.ti.com - I don't speak for others and they don't speak for me. ------------------------------ Date: 26 Jan 93 13:23:03 -0600 From: Bill Higgins-- Beam Jockey Subject: Smithsonian videodisks (was Re: Apollo Program photos) Newsgroups: sci.space In article <19930126133842.Roger.Wilfong@umich.edu>, Roger.Wilfong@umich.edu (Roger Wilfong) writes: > In Article <11748.409.uupcb@the-matrix.com> "george.gassaway@the-matrix.com (George Gassaway) " says: >> I am currently researching Apollo-7 for the purposes of creating and >> documenting detailed drawings of the Saturn-IB launch vehicle. > I too am researching Apollo with similar intentions; however, my interest is > in SA-6 and SA-7 (Saturn I, Block 2).

Oh, well, if there are *two* of you guys out there, there may well be more, so I shall post this old 1989 article instead of simply mailing it to Roger and George... ======== I just received a catalog of aviation history books from the Smithsonian Institution Press. It includes six videodiscs full of stills at fifty-five bucks apiece. I don't have a player, but maybe some readers will be interested. "The National Air and Space Museum is reproducing its entire photo archives aon videodiscs. Ten discs are currently planned...[these laser NTSC 525-line discs] can be played on all laser videodisc players." Two of the six discs are relevant to students of spaceflight. Quoting from the catalog: ============================================================================ Archival Videodisc 6 The Lunar Missions Imagery Disc documents the history of manned and unmanned lunar missions with over 70,000 images. The unmanned Ranger, Surveyor, and Lunar Orbiter missions are represented with a selection of over 6,000 black-and-white images on side A, followed by 23,000 color and black-and-white images taken by the Apollo astronauts. Because many of these images were shot in rapid sequence, they provide an "animated" re-creation of many aspects of the Apollo missions when played in an auto forward mode. Each image is referenced with an index. Also on Side A are chronologies of American and Soviet lunar missions, photodocumentaries of lunar explorations, and biographies of the Apollo astronauts. Details of lunar mapping are provided as a cross reference to the Apollo photographs. Side B stores roughly 47,000 frames of Apollo panoramic photography from Apollo 15, 16, and 17. A mapping index is provided for Side B.

Last I heard they were scheduled for launch in late 1992 or early 1993. I imagine that with the current economic crisis in Russia money allocated for Mir is tight. Perhaps they have been delayed due to the budget. Also, I thought an Israeli cosmonaut was supposed to be launched to Mir aboard Soyuz TM-16. However, Soyuz TM-16, launched a few days ago, only contained two Russians. Has the Israeli flight been cancelled or delayed?
