I love these stories. Back when I was working at a passenger airline we received the Boeing operator's magazine. They once had a story about someone who was retiring after 75 years at the company (she started at 20). The article noted that at the time Boeing did not have a ceremony for 75 years of service (up to 70 only) and had to come up with one for her.
Many of the very long-term employees were women who started by stretching fabric over wooden airframes.
