    RB.106, RB.122 and RB.128 and Zeus turbojets

    We rather need a decent definition of what the RB.106 was, we have a few bits of information and even a rumoured name as the "Thames", which I find a little suspect for a fighter engine, but it does fit RR's naming conventions. Supposedly a 'drop in' replacement for the Avon. RR seems to see it...
