Red Bull sends wingsuit flyers over downtown L.A.

LOS ANGELES, California -- A pair of wingsuit flyers sponsored by Red Bull lit up the skies over L.A. at twilight Wednesday, March 20.

People on Twitter reported seeing what they thought was a meteor or even a UFO, but closeup video showed two people in wingsuits trailing sparks behind them over downtown L.A.

It wasn't immediately clear if the stunt was for a Red Bull commercial or another project by the company. Police sought to reassure the public, tweeting: "PSA: A meteor did not crash into Downtown Los Angeles, and no, it's not an alien invasion...just a film shoot. This is Tinseltown after all."
