It's impossible to forecast retirements at Netjets because we have no mandatory retirement age. As long as you can hold a first class medical, you can keep your job. But I swear, some dudes don't know when to quit. There are some old cats here that won't quit until they're dragged out of the plane on a stretcher. 70+ years old. God bless 'em for keeping on, because this is hard work for a person half their age.
