No way - I fly 80+ times a year. Most are too young to be retired. the majority are way too dumb to be retired Police or Fire Department employees.
Ask them yourself. 20 years in PD/FD makes one 38-40. Many are ex Military after 4-8 years or active reserves. There are many in school. That leaves about 1/2 of the rest of others. But, I’ve talked to many regarding this subject. You’d be surprised.
