The evidence is that cloth or surgical masks, on the recipient, help a little. Cloth or surgical masks, on the source/infected person, help a lot.
But that isn’t the answer you want, so you keep returning to “what if you’re on an airplane”. It asks the wrong question, as a rhetorical device to get the wrong answer.
It’s a silly question. If you are unvaccinated, then you really should not be on an airplane during a respiratory pandemic. The risk to you and others is too high.
There is no real need to ask “what kind of mask should I wear while riding in the aluminum germ tube?”. The simpler answer is ”don’t get in the aluminum germ tube if you don’t need to.”
Then you can go back to the right question. Do cloth or surgical masks reduce transmission from me to others by a meaningful amount? (10% or more)
The answer to that question is a clear yes.
Keep preaching. Admire the faith.
