geek porn video: "The Mighty J58 - The SR-71's Secret Powerhouse"
Six minutes of pure geek pleasure; bet you just saw "SR-71" in the subject line and your mouse finger was atwitchin'. The casual observer would've thought I was watching porn on my computer at a couple of points, when the brilliance of the design of that engine came through crystal clear in this very well done video and caused a few vocalizations of geeky pleasure. It was all in my mind, but they say that the mind is the biggest erogenous zone. Enjoy, you geeky pervs...
