Re: £57million
We were caught napping with Aircraft but soon caught up in design, but they didn't have overwhelmingly high numbers, they just gave the perception that they did which was enough to make us run away even though we on paper out gunned them both on the land and in the air.
You point on the Hurricane is correct, as that was the principle winner as its bigger better brother wasn't available in sufficient numbers until much later. Tanks we outnumbered them by a staggering proportion to start with but their tech was sufficient to kick us in the balls, just enough to make us think we were shafted, again the reality is we were not. Later in the war we did beat them on numbers and not tech.
But it think the point im trying to make is that initial victories for Germany were as a result of better tech and more importantly better deployment, ironically when their tech improved their ability to deploy was reduced through incompetence eventually leading to their downfall.
Numbers don't always mean victory as they will proved to start with, Christ, even back then the RAF and Navy were a each others necks, kinda makes you wonder who pissed of who first! :)
