beg to differ with you,re rather biased view on relative intelligence of people who work within the flying world and their roles related to security.
From where did you pull the figure of 0.0001 % of the population only being able to become flight crew ,I would have to rubbish this.
Cabin crew do have safety and medical training which although not often put into practise could be useful in an emergency situation,(like flight crew ,most of whom will go through their entire career without ever experiencing a real emergency).Day to day they serve tea and coffee,day to day planes are mostly flown by computers,however its when things go tits up that as a passenger ,you WOULD be happy to have a competant pilot and WOULD be happy to have a trained up crew who may just do something that saves you're life.
