I concur with what you are implying and there are many who undoutably should not be flying but that does not mean that it is necessarily right for anyone with any sort of diability to pilot an aircraft for hire and reward. IMHO
So IYHO what would you deem acceptable as a disability to fly public transport aircraft, or do all pilots now have to be 100 % perfect astronaut material, then at the age of 25 be retired.
