Markus Schiller and Robert Schmucker have sent along an Addendum, following up on their original analysis posted here and which  spawned so much press coverage.

The issues it raises continue to be very interesting.  I am embroiled in several very interesting discussions, one of which is occurring in the comments to my previous post, Real Fake Missiles.  My favorite moment has been encountering the acronym BFRC — Big F*cking Red Cloud.  Here are some descriptions I found elsewhere:

The thing that always scared us was, in Gemini, when the Titan [was] flight-pressurized.  And we had that glorious BFRC.  You’re familiar with that term?  It stands for “big fucking red cloud.” See, whenever they had a leak, they said, “Don’t open the elevator door!” It was big red stuff.  You’re talking about nitrogen tetroxide all around us. http://books.google.com/books?id=LWMivGgbM7kC

NTO leakage on the engine test stands at WSTF was known as a “BFRC.” One might hear over the loud speakers, “We have a BFRC on 3!” A new secretary asked her boss, “What does BFRC mean?” Like a pluperfect idiot he told her. “BFRC means Big F*cking Red Cloud.” Shortly thereafter a directive came down from the head-shed that from that time forward, BFRC’s would be referred to as “Propellant Excursions.” I really believe to this day that “BFRC” better described the urgency of the situation. http://www.spacetweepsociety.org/category/space-history/apollo/

NTO, of course, is what North Korea may use as an oxidizer.  I wonder how to say Big F*cking Red Cloud in Korean?
