Just so you guys know one potential source of a lot of "UFO reports" out of Phoenix the next week or so,

There is a HUGE convention of guys flying electric R/C planes (a lot of them lit with LED lights for night flying) at the Phoenix stadium this weekend:

WOULD NOT SURPRISE me at all if some of the guys are 'warming up' by taking their planes out at night and videoing them..... And a LOT of the 'triangular shaped' UFO photos I've seen lately are very obviously park-flyer electric r/c flying wings.

(I'm going to get on a flight myself tomorrow to fly cross-country to the event.)
