A few months ago I was contacted via email by someone looking for information on the North American Aviation “Rotational Research Facility” built in the 1960’s. This was – kinda – an “artificial gravity space station” built on the ground, designed for long duration human testing. Obviously it would not test human reactions to fractional-G environments, since it started at 1 G and went up from there, but it would test responses to Coriolis effects and the like. When I was contacted, I had nothing on it other than a vague recollection of the concept. Thanks to eBay I recently acquired a book that had a short description of the facility, from before it was built. If that was *you* who asked about it, let me know. If it wasn’t you, but you have more information on it, let me know. Google turns up very little on the RRF apart from a few newspaper articles. The whole thing seems to have been memory-holed; perhaps the name changed before it was built.
