On page 9 of Flight International for the period 24-30 September there is an article.
Very briefly, an organisation called the Professional Pilots Federation, (PPF), are claiming that the original setting of the age at 60, by the FAA, was created under false pretences, by Elwood Quesada of the FAA to help American Airlines chairman C R Smith solve a pilots dispute. The PPF claim to have documentary evidence and are preparing to go to court.
Ten pilots are applying to the FAA to be exempt from forced retirement and anticipate this request will be denied, the PPF will then launch a lawsuit and say they will expose the alleged fraud.
Hope this helps.
