New Phoenix lights, hoax or real? Or Disinformation?

Unusual red lights that hovered over Phoenix on Monday night captured the attention of Arizonans and reprised an infamous UFO siting in 1997.
Alas, it turns out it was just a nocturnal prank, according to local media:

On Monday, April 21, 2008, odd red lights appeared in the sky over Phoenix, Arizona. Video and photos were taken and Air Traffic Controllers in the main tower at Sky Harbor International Airport saw them. The FFA says that the lights did not appear on radar and weren't a threat to any air traffic, so no action was taken. However, the FAA has issued a statement saying that they will not allow the Air Traffic Controllers to talk about what they saw:
