I think where you are going with pre-flight testing. Even if we get numbers way down by containment measures like a complete shut down, the virus will still be there and we will need to very actively test and trace (see below article). For that to work, fast test will be invaluable. Testing everyone who is traveling or going to large events or even better just going to a grocery store would really help to get back to something that's somewhat normal without having to shut everything down again periodically or losing millions of people in the process.
