Sorry Ruy, I simply can't reply now but I'll just mention that you're being unfair to the British about their aerial effort in May-June 1940. I think they really did all they could do over NL-B-F. The outcome of the BoB really could have been different and Britain would have been more comfortable without the losses suffered over the continent but then, Britain had been first to declare war on Germany so a war, which also means losses, must be expected.
More some other time (?).
