I'm only getting more confused by the terms people are using. Airborne for me means...measles--floaty particles lingering around--which this doesn't look like at all. Or at least not nearly as infections. I suppose I'll continue hunkering until there is consensus. *hunkers*

Not likely, but also not impossible, if the wind happens to be blowing just the right way.

Nothing's impossible, but in most places where contact tracing has been sufficiently good the vast majority of cases are from close contacts rather than happenstance interactions
