Not as many of us but a similar tale for my lot... Grandfather joined in 1928 as a rigger, on Blenheims in WW2 then retiring sometime in the sixties as an Air Cdre nav. Dad joined up just before grandfather retired (followed by both his brothers later). I then signed up in 89 - dad retired early in 92. Great uncle on father's side was a pilot on Sunderlands during WW2 also.
Continuous service for nearly 80 years. Interestingly enough my grandfather's first sqn, 24, was also my first sqn. Additionally he and I were both members of 30 sqn when we first found ourselves in Iraq.
