OK Ferrydude,
If you're happy then great.
For fighters - so in a way much the same thing as an airliner doing X cycles - Lithium alloy was regarded the ultimate material for both immediate stress and for maintenance.
Guess what ? - It requires skilled people, remarkably similar to those laid off in their thousands over the last few years ( no, I'm not one of them ).
Safe travels, but maybe ' think brittle' !
Happy Christmas,
Double Zero & Muttley
