It's eerily quiet out there. I was on the ramp at an airport that usually makes the top ten or fifteen list for the most aircraft movements in the country, and during the pre-flight briefing I could hear frogs croaking in a distant ditch.
In the air I'm having the sort of chats with air traffic controllers that usually happen at three a.m. I can ask for direct just about anywhere from anywhere and get it instantly. I've a few times called up and had the controller reply "is that [airplane that's not me] calling for [something irrelevant to me]?" That seems to mean that there's only one airplane in that controller's airspace, and the controller wasn't expecting it to want anything in the near future, so kind of zoned out. Maybe conducting a conversation with another bored controller, at a desk two metres away.
I asked a military controller whose airspace I was working in if he had other traffic on other frequencies, but he said it was just me.
Even in the sky we're isolated. Many thanks to all the people staying home, and staying away from people and places they'd love to visit, so that when some of us get this disease despite everyone's efforts, the hospitals are not overwhelmed and we have our best chance to recover.
