I thank you for that.
Mr. Chair, I guess I want to ask again why we made a change to the rapid antigen test that we know is not sensitive in asymptomatic individuals, because, if you're symptomatic, guess what? You're not getting on an airplane. The question remains as to why we would recommend this change. Why would we keep it at all? That doesn't make any sense to me. I guess this is the third time I'm asking the same question, so why? I really would like an answer.
