Search is you friend. This exact story was posted three different times yesterday.
The "search function" (If you can even call it that...) here at FR is about as useful as tits on a boar hog... right up there with the edit post function.
A 1950's era Russian Inertial Navigation System is more intuitive to use...
Does it matter really? Look how many people found this one. So it was posted 4 times. Must be a pretty significant story. I wouldn't have searched and found the other three, I just stumbled on this one because it was recent. No harm done, unless you can think of one.
