Out of interest as a UK resident, how does the US support it's huge network of GA airfields? From my experience these seem to be well funded, impressive and well supported, despite being relatively little used. i.e. I can think of many airfields with huge tarmac runways, impressive hangarage and facilities that may only get a couple of movements a day. It seems a shame that we don't have the same level of committment in the UK.
Also as an aside, with the rising interest and development in future personal transport being autonomous flying vehicles such as the multirotor taxi deisgns around at the moment, shouldn't the Government start thinking about protecting tha airfields and infrastructure that will be needed to support these. Once lost, the Government will never get the land back for airfield development.
