Well, whatever impact it had, it was well worth it.
I was driving through Bethnal Green (East London) yesterday (Sunday), and heard a most unusual aircraft engine noise. I looked up through the sun roof to see a Lancaster bomber, with a Spitfire on one wing tip, and a Hurricane on the other, in perfect formation at about 700' agl right over the top of me..
It took about five minutes for my hair to lie down again, no exageration. They looked and sounded fantastic (six Rolls Royce Merlins?).
