One of the main features of the former Naval Air Base at Moffett Field, outside of San Jose, is Onizuka Air Force Station. Known colloquially as “The Blue Cube”, the large, windowless blue building is the subject of no small speculation in the area. Until its recent decommissioning, the building was known to house an Air Force satellite control center, suspected to the MAIN satellite control facility for much of the United States’ satellite inventory. The building was, perhaps unsurprisingly then, rumored to be the world’s prime nuclear target. Meaning that if the bombs started falling, Mountain View would be the first place to go. Let’s do a little math here. Moffett Field is about 11 miles from the heart of San Jose. A 25 megaton nuclear bomb (about half the size of the largest ever tested) has an utter destruction radius of about…well…11 miles. Given the blast expansion formula R=S(Et^2/p)^(1/5) where R equals the radius of the blast, E the energy, and t the time, we get (17,700m)^5*1.3kg/m^3 = ~1(1.05×10^16J * t^2s), so…t^2s = 21,509, meaning…that about 2 minutes and 26 seconds after WWIII officially started, your watch would stop working. It’s probably for the best, really, because you wouldn’t need it after that; all your appointments from that moment forward would be of the more…eternal…sort. Anyway, Greetings from Sunny San Jose!
