The fragility of GA is something this measure (shutting down flight instruction ignores). GA has been teetering on collapse even before this. FBOs struggle, and routinely fail or change hands. Municipalities struggle to fund community airports. Flight schools fail frequently. Major aviation manufacturers and parts suppliers fail or merge (Mooney, Mattituck, etc.). The pilot population has collapsed in the last 30 years. If flight schools fail, that will be a bigger problem. The municipal funding for airports will be under severe pressure after this, because of huge tax shortfalls during this massive economy shutdown. What I am saying is that there may be no GA to return to, if we insist on shutting down the last little thing.
