I have to differ from this. First of all, flight instruction is an infinitesimal part of the population and economy. It’s one person meets one person, not a crowd. Certainly safeguards can be made before meeting in the cockpit. Wash hands and face throughly, wear freshly laundered clothes. Of course have no symptoms beforehand. Also, this needs to be put into context. Everyday you go to groceries, drugstores, pump gas, open delivered packages, pass currency, pay at touch screens, and much else, that either directly or indirectly involves touching where others have touched. So, why such an emphasis on the meeting of 2 individuals who, after all, can take reasonable precautions? Must every facet of the economy be destroyed ? It should be pointed out GA hangs by a thread. The declining pilot population and financially fragile aviation infrastructure make this a real threat to its continuation. We shouldn’t be overzealous in shutting everything down.
