The military used to give pilots straight up meth. They still do give their pilots performance enhancing drugs. How many pilots fly drunk? Why are the checklists not done and confirmed digitally instead of relying on fallible human pilots, regardless of i how much Adderall they're on?

If this were really about safety, there is so much other actionable low hanging fruit to make things safer. Looking at the TSA and ask the security theater there. It's not surprising.
