I have watched BB now well over 20 times (I have it on DVD, and CD for the soundtrack, along with the historical record of the event in the book
The Narrow Margin) and it will always be classed as my favourite film. The music and well as the tremendous photography, with a real (Spanish) squadron of WW2 era Heinkel HE111 type bombers and ME109 type fighters, along with Spitfire's and Hurrican's make it a real classic. At the time the world's 35th largest air force!

But it was in the West End my boyfriend took me to see it in 1969 when first released, and on wide screen it is extra special!!

However if you want a full day by day account of the great battle, I would always thoroughly recommend
The Battle Of Britain Then And Now 5th Edition Ramsey, G. (Editor) After The Battle (2006)
