OK,so you take a swab from every arriving passenger at LHR. All fairly straightforward and resultant delays probably accepted as worth it. What then do you do with these passengers? As far as I know test results take 48 hours to come through. Do you keep everyone at LHR for two days? Do you have huge isolation 'hospitals' where they all go? Or are they released into 'the wild' and contacted if their results are positive? A good idea in theory but needs a bit of work to make it effective.
