People board aircraft on a daily basis. They trust the science and engineering of the flight industry, and the skill of the pilots, to get them to their destination safely.
Yet some of the same people won't trust the science behind vaccinations, because some populist looking for an audience to grift tells them what they want to hear. Vaccinations bad.
Nobody would trust a person who has only driven a car to fly an aircraft, but when it comes to medical science, they think a chimpanzee in the cockpit is OK.
