IF
the chance of encountering someone who is contageous is < 1 in 5000
AND IF
the chance of death on catching it is < 1 in 1000
AND IF
the chance of catching it from someone sharing your cockpit is <1
THEN
what is the risk? <10^-6 to 10^-7 ?
should training still be discouraged (banned) or is it a matter for common sense yet?
