It's another sighting of a jetpack in the skies near LAX recently.
According to a statement from the FAA to KNX 1070 News Wednesday, "A China Airlines crew reported seeing what appeared to be someone in a jet pack at an approximate altitude of 6,000 feet, about seven miles northwest of Los Angeles International Airport around 1:45 p.m. Wednesday. The FAA alerted local law enforcement and will look into the report."
In September, audio could be heard from an American Airlines pilot telling the LAX control tower "We just passed a guy in a jetpack."
