in the UK there seems to be a fairly healthy group of "airplane archaeologists"
someone named alan gough wrote a final paper on them for bournemouth polytechnic (before it became bournemouth university), and decided it wasn't really archaeology (mostly looking for the registration numbers on the engines of spitfires buried in fields)
there are also various airfields, etc., on the protected monuments list, and english heritage put out a fairly good booklet a few years ago about ww2 sites
here in germany there are a lot of concrete bomb shelters in various city centres; these are huge block-like towers that used to have anti-aircraft guns on top of them; my understanding was that most of them are still standing only because their reinforced concrete made them too hard to tear down (one exception being either in tiergarten or zoologischer garten in berlin)
so: besides using planes, there are also remains from installations designed for shooting them down...
peenemunde also has quite a good centre on V1/2 construction & testing
