From The Telegraph:
Face masks should be mandatory on planes and trains as it reduces coronavirus spread by 98.5 per cent, the Chief Executive Officer of Ryanair has said.
Michael O'Leary told BBC Radio 4's The Today Programme: "If you really want to do something that's effective wear masks.
"If everybody is wearing masks you eliminate the risk of spread of Covid-19 by 98.5 per cent. So let's take some effective measures."
It comes as a considerable amount of Britons return to their morning commute today following a slight easing of lockdown.
Is this figure true and if so, from what scientific study is it taken?
