(Sorry, this has nothing to do with the shuttle, but I thought you guys would know something about this...) In a recent computer magazine advertisement there is a picture that looks a lot like a rocket sled experiment. The advertisement consists of three still photographs. In the first photo there is the face of a very clean cut looking white male, possibly in his early thirties, wearing some black eye protectors. In the second picture his face is disfigured and in the last photo his face is very stretched and compressed generally all messed up. Does anyone know what was happening in this photo? (If I had a scanner I would post a bitmap for you.) I want to know if the man in the photo survived this experience okay. When and why did the even take place? Were the eye protectors added tothe photograph by an artist of did the man really wear them in the experiment? (I think they look fake.) If it is a picture of a rocket sled experiment, is there a book that has more information on such experiments? Thanks, Alfred broderic@rutgers.edu

This is very probably from John Stapp's rocket-sled experiments, in which he was exposed to very high decelerations, 40+ gees as I recall, momentarily. A good book on aerospace medicine would probably have more detail. -- NFS: all the nice semantics of MSDOS, | Henry Spencer at U of Toronto Zoology and its performance and security too. | henry@zoo.toronto.edu utzoo!henry

I believe Tim is not making this as a post for rec.humor, but mach 6 air blast is too much to swallow. I do not know if erosion of the flesh or kinetic burning or impact concussion will kill the poor fellow first, but anyway it a spectacular way to go. From Alfred's description, I think it is about the human g-limit tolerance test done by an USAF colonel and probably there was a NASA type report on the results. I remember seeing similar pictures in a high school Physics text and also heard an AE professor talked about him. The colonel was probably the most macho man ever, volunteered himself for research and came back once with a broken limb and another with his eyeball in his palm, after it was popped out of it socket by the g-force. I regret that I can remember his name. Just call me `Man'. "And why take ye thought for " -- Matt. 6:28 raymond@jupiter.ame.arizona.edu
