I had considered starting apost on this very topic, but I stpped myself, for the reasons you mentioned amongest others.
Yes it was a great technical achievment, flying at 60ft with nothing but a couple of spotlights to tell them they were at 60ft, a bouncing bomb.
Though do we really glorify war when we mark these days? Or is it a way of commerating those who fought for our freedoms? Perhaps in this case it is because it's the 70th anniverdsary of the raid it is getting attention, will the 71st anniversary garner as much attention?
Think about it the 68th Anniversarry of VE day passed by just over a week ago, and I don't recall seeing a thread about it. In many respects perhaps the one day in the UK outside of Remembrance Day and/or Remberance Sunday that perhaps gets a bit of attention would be the 15th September Battle of Britain Day
