Pilots are also trained for flight with poor visibility (for example, flying above clouds and looking for holes of clear sky to descend through, then looking for safe landing sites), and also landing with poor visibility, for exactly the reasons we've both brought up. I agree that it's more hazardous, but like I said, it's not falling out of the sky because someone pushed the wrong button on their equipment.

And not for nothin'; if someone keeps screwing up with short disruptions, or (even worse) leaves something on that causes consistent communication interference, the hams will find them, and the feds will start knocking on the door pretty quick.
