Basically says the Flyers Association is being dissolved, decided on 23 April 2019. The 20 million CHF needed to restore HB-RSC has not been guaranteed.
There is a mention that this is not definitively the end of the story and efforts continue to save the situation.
Sounds a rather forlorn hope though.
