I was involved from the union side at national level with the move from 60 to 65.Whilst I.m told the science supported that move for two crew operations if the same scientific criteria were followed for single crew ops the retirement age would have gone down to 55.Perhaps let sleeping dogs lie or go 2 crew! I retired from multi crew flying just short of 63 with hindsight I believe 60 would have been a better age for me to have retired.All down to individual circumstances but I,m not sure the medics can be trusted to filter out those who need to be.Regards Stampe !
