I worked in a crew with Oswalt's father-in-law at Brown's Ferry Nuclear Plant near Athens, AL (the one referred to earlier as having to shut down after having power cut to it). Incidentally, Brown's Ferry is of the same design as the plant in Japan that is experiencing all the problems. Having personally been inside the reactor drywall of that plant, an F-5 could not damage the core. No chance. Losing power, however, is the same thing that caused the problems in Japan. It takes power to keep the reactor at a safe operating temperature.
