Show me the statistics or studies that show that the mask policy on airplanes in the US as of today (aka hundreds of people in a small, closed environment with no fresh air, where mask are taken off for long periods of time and then put back on again) reduce spread of COVID compared to if there was 100% masking (presumably would reduce the spread) or no masking at all (basically the currently policy) I understand statistics, you have no statistics to back up your claim. Just so we are clear, I think masks do work if they are used properly - they are not used properly on airplanes in the US, so they are pointless. |

It's not a study from the US but it includes enough flights where there were confirmed index cases and there were 4 levels of masking rigidity. The case we're describing, where people only unmask to eat, there were no transmissions.
> On flights N–R with the rigid masking policies (meals served) of Emirates Airlines, no secondary cases were identified on Day 14 screening despite 58 passengers who were PCR+ on a total of 5 flights of 8 hours each with ~1500–2000 passengers.
