Ok Foghorn, I'll bite. Unless the purpose of you posting to a public forum is to tell everyone else that you're the expert and we should all mind our own business, why don't you explain to the rest of us, in words that we would understand, how it is that the T1 fleet has gone from being good to fly for another 20-odd years in 2015 to being knackered and ripe for retirement in 2020, and how the fleet has managed to achieve this with more than half of its airframe hours remaining?
Don't break OPSEC, obviously.
