Personally, I think you are being too hard on the CDC to say that “they clearly know nothing”.
There has been a learning curve; this is, after all, a unique situation. I think most of us as pilots are science-based creatures. And, even if they [CDC] have modified their guidelines as research and realtime experience dictates… I’m still far more inclined to follow the health professional’s advice over political talking heads.
And while the media and society are moving on, the professionals are holding their collective breath.
I am too. Cases are still rising in nearly half the states. I’ve chosen to wait a little while longer before I shoe-horn myself into a 172 with a CFI.
