From an overseas perspective I dont think it was unreasonable for UK GA traffic to be grounded during the crisis. After all, a blip on radar is a blip on radar, regardless of whether its a C150 or a 747 (assuming transponders and any other identifying computers off of course). Better to be safe than sorry, noone knew what the heck was going on for a few days after the horrid events of a fortnight ago.
