New bloke, aha ! P.1127, and the proposed supersonic development was the P.1154 ( I think). Did you have anything to do with that, JF ? I'd also like to add a note of appreciation for your taking the time to answer queries such as this topic's. Actually while I'm at it there's a few other blokes who usually give good gen, like Watford and Tinstaafl. Thanks, keep it up. I appreciate it, anyway.
Cheers DB6
