I think the whole system is backwards!
Flight instructing has to be one of the most important, if not THE most important , job in aviation. In any other industry, the guys who reach the top in terms of skills, expertise, etc. are the ones who teach, yet we do it the other way around! Retired airline types should go on to instruct!
Also, friend of mine, (instructor, teaching people to take 3,000lb metal and plastic machines up over congested areas with potential death and destruction if mistakes are made!) gets $12/hour. She is also taking ballroom dancing lessons. The Dance instructor charges $120/hour!
Time for a revolution...?
