From a retired NASA employee and long-time NASAWatch reader:
"Keith, the attached photo was just too instructive to pass up. Let me explain. This is at the Gilruth Center at JSC.
I believe that it visually shows the risk averse nature of NASA and says something about space politics. I.e., one stop sign wasn't enough. A second one is safer. And then a sign explaining what a stop sign means. Man are we safely redundant.
I am a retired NASA engineer and could not pass up the hilarious sight.
Enjoy."
