Glad he survived what sounds like a very tricky situation. I would guess that he retired on his old COS at 55 about 3-5 years ago from memory. 58-60 is my guess unless having flown with Old Fella on the 707 as a primary school kid, he joined CX in the late 80's as a teenager!
Anyway, super chap and very relieved he's OK. Is there such a thing as a 4 engined 'lighty'? If so, buy one Steve!! All best, Mate.
