Dan,
How about we extend the retirement age for policemen and firemen too? Would you like a 60 year old fireman carrying you out of a burning building down a flight of stairs? It would be dangerous. Not all of them are out of shape or weak, but most probably are. Same with pilots. After 30 years or more of flying, the reflexes go, and so does the hearing. It is best for everyone that they leave and not have the responsibility of carrying around 200-250 people etc. If they want to fly corporate or for fun, they should go for it, since it would likely involve less lives in the back.
The only reason this whole deal is being brought up really is because some pilots are now having problems with their pensions. This is a good lesson for everyone, to create your own portfolio, instead of hoping a faulty promise will come through. Our "excuse" for wanting to upgrade faster is equal to your "excuse" about not planning for yourself outside of company promises. The rule is there for a reason, and the Supreme Court ruled against those Southwest pilots who sued for discrimination.
Bye Bye--General Lee
