The CDC just said yesterday that they confirm airborne transmission, and from the case of the choir whom was 6 feet apart, it sure makes it seem beyond one table worth.
"The U.S. Centers for Disease Control and Prevention (CDC) on Monday took down its guidance warning on possible airborne transmission of the novel coronavirus, saying that the draft recommendation was posted in error."
The question isn't whether it's possible at all. It is, I don't dispute that, but even post-vaccine we'll never reach a point where it's impossible to transmit the virus. The question is how high the risk is relative to other things.
