A man has shared a strange video of a 'flying item on fire' above Los Angeles, California, asking fellow Twitter users what the hell it was.
Posting the bizarre clip on 21 March, Dennis Hegstad wrote: "What is this flying item on fire above downtown Los Angeles?"
With the video racking up 48,000 likes and 16,000 retweets, it was evident that Dennis wasn't the only one left feeling a bit baffled at the fiery scenes.
It turned out many others had also spotted it, with one person tweeting: "Holy shit just saw a meteor fall from downtown LA on the 10 East #wtf."
Someone else commented: "Saw it too. Thought we were done."
But, as with most seemingly inexplicable things, it transpired there was a perfectly normal reason behind it - as Red Bull later admitted it was behind the spectacle, which had been celebrating that evening's supermoon (the final one of 2019) and the start of spring.
For the stunt, skydivers wearing wingsuits fitted with LED lights and 'sparking pyrotechnics' launched themselves from a helicopter 4,000 feet above the city, whizzing through the sky at 120mph.
"Wearing wingsuits that shape the human body into an airfoil, they leapt from a helicopter 4,000 feet above LA and swooped into downtown at more than 120 mph," Red Bull explained in a statement.
"To add a touch of Hollywood glitz, the suits were fitted with LED lights and sparking pyrotechnics that lit up the night sky as the sun set and the supermoon rose.
"Travelling three feet forward for every one foot down, their southwestern one-mile flight took them past the InterContinental Los Angeles Downtown hotel - which at 1,100 feet - is the tallest building west of Chicago.
"They finally pulled their parachutes at 1,000 feet and landed safely on the city streets below in the first ever wingsuit jump into downtown Los Angeles."
The three skydivers - Jon Devore, Mike Swanson and Andy Farrington - have a combined total of more than 70,000 skydives between them, and completed two jumps for the stunt.
The Los Angeles Police Department also took to Twitter to explain what happened, saying: "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."
Okay, it wasn't actually shoot for a Hollywood blockbuster - but it sounds like it certainly became enough of a spectable to rival one.
