You must admire how the Americans play around with concepts. Even if we had the capability, could you imagine any European country actually having a go at dropping an ICBM from a transport aircraft?
Another one that always impresses me is the C130 gunship - "Hey, let's put a big gun in the side of a C130".
......or landing a C130/U2 on a carrier.
Of course, some of the ideas are barking but at least they give it a go.
