TOTD - you forget I am still working within the military training system and painfully aware of the slow-motion train crash that will be the changeover between DHFS and MFTS.
MFTS will have to succeed since there is no plan B - much like UKSAR - but it won't be a painless transition - much like UKSAR (have they met the terms of the contract with aircraft yet???).
The start date of MFTS has already had to be slipped to the maximum which tells you a great deal - some wonder how cutting the bid to the bone with numbers of aircraft will work in practice.
I'm afraid this blinkered belief that new and shiny is always cheaper and better is one only shared by those with a vested interest and those who can't see past the sales pitch.
