Disso nearly done

Just two tasks still to do on the main body of the disso - add in some 'colour' from Life's coverage of John Glenn's Friendship 7 flight, and then cut about 750 words from the whole piece. It all has come together, and now I've just got to be brutal on the editing, cutting out all the nice to know rather than necessary to know stuff. There's a week to go on this, then a week off, and then straight into my new PhD work.
