Good plan. And I suggest that you fliers stick to traditional navigation with sextant and dead reckoning. Ernest Gann used it, and the technology is still being used.
Vaccines based on live virus carry a particular set of risks that mRNA (and other) vaccines completely eliminate. Sure they MAY introduce other risks, like modern nav systems raise the risk of collision as everyone flies the same perfect line between two points. But on the whole, I will take the overall improved performance.
