I was nearly going to make a silly remark about it being because of Corvid-19. But bugger me it is. This pulled from one article.
“We believe is that there is minimal likely risk to a pilot flying solo, providing pre- and post-flight social contact is minimised. There is clearly a greater risk of virus transmission if two or more people share a cockpit, but this risk is no greater than if they were sharing a car on the highway.
“Currently countries including Belgium, Norway and Italy have closed their airspace to VFR flights. I understand too that other Baltic states including Lithuania may have similar restrictions. Sweden and Denmark appear to have no blanket closures, although one or two airports have been closed, again due to staffing issues.
