The 70th anniversary of the start of the Blitz will be marked today with a memorial service and a flyover of period aircraft. The service at St Paul’s will be attended by those who lived and worked through the onslaught, including nurses, pilots and fire-fighters. There will also be plenty for the general public to see, with a military march-past outside the cathedral. If you’re in central London, look to the skies around 12.30 for another flyover of historic aircraft, including a Spitfire and a Hurricane. Meanwhile, Radio 4 is running a series of short programmes on how the Blitz affected other cities around the UK, and the Culture Show considers the art of WWII.
