Let me ask those against the rule change just what is your objection? Is there any imperical evidence that pilots are not capable of meeting medical standards beyond age 60? Is there any imperical evidence that there would be a higher bust rate on checkrides for those over 65? Just what are your objections based on? The only arguement I've heard that isn't complete Bulls**t is that it will delay YOUR upgrade/transition/payraise. It is the very same greed that you accuse the senior pilots of guiding their decision. Did anyone notice that your said upgrade/transition/payraise will still happen, just at a higher rate as you acquire longevity? And those last 5 years, should you choose to accept them, will also be at a higher rate. But I will be assuming that all objectors will voluntarily retire at 60, right? Or are your arguements just oral diahrrea?
This retirement age was determined, as previously stated, in 1949 and was established at the request of airline management. It was created simply to hold down payroll of all the WW2 vets that made up the bulk of the seniority lists of the day. It was a purely financial decision, backed up with smoke and mirrors medical science. Even if it was remotely applicable in 1949 the average life expectancy of a US citizen has increased almost 20 years since then. All credible contributors agree that there is no longer any medical reason to require retirement at age 60.
So, have at it, gentlemen and ladies. Come up with something other than "get the f**k out of MY seat" and I'll be happy to listen. Otherwise, wallow in the same greed that you accuse others of.
