The FBI is investigating reports that a “guy in a jetpack” was seen by pilots flying near Los Angeles’ LAX airport nearby to where planes were landing.
The incident, which was recorded by air traffic controllers, happened on Sunday evening and was witnessed by pilots on two separate planes.
The apparent culprit was seen flying at an elevation of 3,000ft (915 meters).
Jetpacks, once the realm of science fiction, have become a thing of reality in recent years, according to experts.
“Tower, American 1997 – we just passed a guy in a jetpack,” the pilot of American Airlines flight 1997 from Philadelphia told officials in the control tower as he approached LAX around 18:30 local time (01:30 GMT).
“Were they off to your left side or right side?” the controller responds, leading the pilot to say the person was 300 yards to the plane’s left.
Within a minute, a pilot flying JetBlue Flight 23 also reported seeing a man fly past. As the controller advised the pilot to be cautious, he added “Only in LA”, according to LiveATC.net, which records air-traffic control transmissions.
The FBI and the Federal Aviation Administration are both investigating the incident.
