A ‘chain’ of lights flying across the skies above Holland sparked fears of World War 3 - or even an alien invasion.
But the ‘invasion’ turned out to be tech billionaire Elon Musk’s plan to launch thousands of satellites and deliver internet from space.
Dutch website ufomeldpunt.nl had more than 150 sighting reports after the Space X satellite passed over the country.
Viewers described, ‘a bizarre train of stars or lights moving across the skies at constant speed’.
People described it as a ‘star caravan’ and noted that the ‘UFOs’ were travelling faster than planes.
Space X launched the first batch of 60 small satellites into low-Earth orbit on Thursday for Musk's new Starlink internet service.
A Falcon 9 rocket carrying the satellites blasted off from Cape Canaveral Air Force Station at about 10:30 p.m. local time.
Musk hopes the Starlink satellites will generate cash for his larger ambitions in space.
