Having been otherwise engaged earlier, I managed to see a little TV footage of the Biggin event on the 10 pm news bulletins, They were followed by Newsnight on BBC2, which offered a more down-to-earth, intellectual assessment by Evan Davis, who then interviewed a couple of experts.
I hesitate to disappoint any of you, but this Battle of Britain thing is largely a myth that was originally cultivated to improve our parents' and grandparents' morale while it was going through a wobbly patch. The war fought by the Russians in the eastern front, as you should all know by now, had a far more serious and significant effect on the outcome of WW2. After all, would it really have made any difference if the Germans had taken over Blighty?
Thank goodness that in this modern world of ours we have the benefit of the authoritative and enlightened perspective of talented BBC editors and presenters to debunk the exaggerated tales of the heroism of that generation, and present a cool, rational analysis...
