I was at a client's site. Meeting stopped, Video Conference turned off and TV on watching it unfold.
My best friend was in the US having a flying lesson in a light aricraft when they closed US airspace. They were told by air traffic control to land within 20 minutes or they would be at risk of being shot down. Quite scary as no explanation was provided while they were in the air.
My brother was filling in his application form to apply for BA's trainee pilot scheme. Less than a week later, it was in the bin.
