Time to roll out these 15min test kits. Test the test kits. Get 20 people 10 already covid positive and 10 that are not and check the accuracy.
If all 10 positives are accurate and the other 10 are negative as per the real covid test then impliment these immediately.
All the negatives fly on the day. Even if it means arriving at the airport much earlier do this test and if
all good everyone in that pressurised tube is covid free keeping borders OPEN.
