The recent wave of UFO sightings in Northern California continues, this time in Oakland. On May 28, 2010 a V shaped UFO was filmed around 10:00 pm.
The video looks similar to the Fremont video shot in December 2008, but I think these are separate craft flying in a tight formation. If you look at the lower leg, the spacing of the white lights is different than the top leg. Still, whatever these craft are they are moving at a high rate of speed and in a tight formation.
If they were conventional aircraft you would see a strobe light, but not on these. My theory is that it's some sort of terrestrial form of aircraft, albeit it a some sort of secret one.
