Free is such a good thing that free electrons will soon be
given a page. Non free electrons are in transistors and
lasers. By the way, light comes from electrons changing
energy levels. So if that UFO on the VELOCITY PICS page
is not a plane with lanterns hung on it, maybe the lights
are connected to the propulsion system.
Not very stealthy.
