Funny, slightly disturbing, story: A helicopter cameraman for KCBS in Los Angeles shot footage of a mysterious “missile launch” near L.A. yesterday evening. All four branches of the military have denied they were involved, and the Pentagon continues to look into what it calls an “unexplained contrail.” Well, a Twitter user in Wales might have cracked the case while the Pentagon is still investigating: Iron Man director Jon Favreau just retweeted the user’s original tweet: “Unaccounted missile launch in California? Or billionaire industrialist testing newest armour?”

What say you, PopWatchers?
