So how is it that the FAA comply with their international obligations and yet are able to give the user a graphical interface?
a) Funding by taxpayer, and
b) They prevent every tom dick and harry (usually trying to cover their ar*e, by reporting a duff light bulb on some lamp-post) injecting nonsense into the system (within the USA), and
c) I don't think you can use the FAA facilities to get a briefing for a flight from Goodwood to Bembridge (even though a decent bizjet could fly from the USA, to Goodwood, and onto Bembridge
) Even though the UK data should be in their data stream!
