Given age 18 as the absolute youngest anyone has ever been hired by a major airline, no one currently flying Part 121 in the US was hired before 1961. I'm assuming the days of DC3 to 747 careers are rapidly dwindling if not already gone.
Does anyone know when the last former captain and last former FO on a DC3 for a US major airline retired?

DC8 (probably still many around)
707 (ditto DC8)
