Knowing that some very senior RAF officers read this thread:
Rumour control: The Hawk 115's at NFTC might be up for sale in about 3-4 years......
They would make a cheap replacement for the T1's and not dig in to the 128 pile, and there's 9+a few spares of them 'allegedly' available.
Snag is that The Snowbirds may be about to buy them (more rumours)
to replace their old steeds.
