A good aircraft, and I like looking at the two at Duxford, but I've never really had much interest in it. Still, they provided sterling service, and I think us taxpayers got value for money over the years.
I thought it was "Must Replace Canberra Again" (attempt #1 being the TSR.2) or "Mother Riley's Cardboard Aeroplane" (a reference to its intention of being multi-rôle aircraft, something which turned out to be harder to achieve than thought)
