As I have said its cock all to do with the issues you are mentioning, its all to do with the residents of a country circumventing national law.
It goes far deeper than the NAA's which is why "they" have pushed it through by hook and crook and spent so much time and money doing it.
And the "they" are Sir Humprey types (google "Yes Prime Minster" for the none UK folk)
And I don't know if they FAA does for UK owners maybe all the UK planes have trusts listed as the owners. And would they release the data anyway? I would presume so with all the US residents likely to be at the Olympics but who knows.
And I know you are right I could do the same for a few G regs as well. BUt thats not threason why they are pushing it through.
