FACTS.
1. No one is crediting pilots with superhuman powers of observation.
2. Of the approx 13,000 tests per year, the normal number of positive tests (above 0.4 BAL vs driving limit of .80 BAL) has been between 5 and 10 per year. Not 5-10%, thank goodness. 5-10 total failures out of 13,000 tests. That is an extremely small percentage. That small number is the reason the FAA only does 13,000 tests.
3. Yes, a pilot "will kill a heck of a lot more people than a drunk driver." And that sounds quite sensational. But if you look at the number of people in the US actually killed by drunk drivers vs the number killed by drunk pilots in the past forty years, the count is something like 1,600,000 to 0. The last fatal accident in the US of an large commercial jet was on a cargo airplane, in 1977. All 5 people on board died. So, 41 years, times 365 days, tines 87,000 flights per day means 1 in 1,301,995,000 flights. It doesn't seem to be a major issue.
Your reporting of the pilot stats is very similar in style to the media's reporting of UAS events. It seems as if you are trying to scare people and sensationalize this particular issue at the detriment of the safest transportation system in history. And as for your "superhuman" comment. Even in the original Superman movie, the man of steel said that flying is still the safest form of travel.
Fly safe.
