That is one way you could describe Azriel Blackman. He began working as an airline mechanic for American Airlines in 1942. And, he is still working today, as he awaits his 92nd birthday next month. He works eight hours a day, five days a week. Azriel starts at 5 a.m. and works until 1 p.m. Note that he drives himself to work.
He is a crew chief who reviews paperwork detailing what maintenance has been completed and what remains to be done on 17 jetliners that are kept overnight at the airport. And then he walks around to review the work that is being done.
He is listed in Guinness World Records for the longest career as an airline mechanic.
