German WWII bombing raids - targets?

[john_p]

Bucks County Council have put an online map of all bombs that were dropped in the war in the county

Looking at the map I am really surprised how spread out the "air raids" were in 1940.

Previously I thought they were all targeted at centres of industry (initially) then the major population centres as
the war progressed - looking at this there seems to be a huge amount of bomb raids that hit farms, rural villages, etc. (I am not sure if a bomb icon on the map relates to one or many bombs)

Was this deliberate or just mistargeting, bombs being dumped after raids, and the like?

It seems all the Bucks airfields I can think of were unscathed by bombing raids, on that map.

That said I would assume records of bomb raids on airfields would have been kept secret, so maybe the councils were never aware of them..
