The rocket was undergoing a static fire test of the stage, in which a vehicle is clamped to a test stand while its engines are ignited, when the booster broke free. According to a statement from the company, the rocket was not sufficiently clamped down and blasted off from the test stand “due to a structural failure.”
Video of the accidental ascent showed the rocket rising several hundred meters into the sky before it crashed explosively into a mountain 1.5 km away from the test site.
The Falun Gong was originally an ally of the CCP as recently as 1993. They had a falling out when some of their chief leadership got caught in a string of financial scandals and abuse allegations. Attempts by the state to begin prosecuting church leaders triggered an outcry from the membership, which prompted more arrests and more efforts hide the organizations money, and finally a wholesale exodus from the country by its most devoted members.
Falun Gong leadership arrived in the US and immediately began churning out anti-China spin, with the help of the Epoch Times - an originally Chinese-only paper primarily distributed in Chinese ex-pat communities by church refugees. If you get into the history of the Epoch Times, you should very quickly discover that it is not a reliable source of information.
Which isn’t to say China’s been great wrt religious freedom or free association. But the modern incarnation of Falun Gong has more in common with Scientology than, say, Mormonism or Baháʼí. You’re going to fall down some really QAnon-themed rabbit holes if you take everything their community is saying at face value.
