Oh dear , sounds like EK have got OLD C****y Syndrome............ie , lets scour some obscure tech manual and ask some poor 'average' pilot a question which even I have not heard of ...........what fun !! Apparently I should have known a LOT about Kevlar etc . Sad thing is , the git who tortured me was later fired for a VERY NEAR miss with terrain somewhere in the newest Chinese take-away (1997) . Apparently its very hard to see Cumulo-Granite when your eyes are welling up with self-importance and pommie-bashing mania. I really should have been in the right squadron heh ?
Strangely , have managed to get on and fly various large jets both with and without Kevlar since ..sounds a bit risky / dodgy non ?
IAB -its all bo............
