In a previous article, said:
So is this one (or perhaps the main) reason that airnav.com doesn't
have any Canadian info? Is this something you plan on adding or is it
too difficult to deal with Nav Canada?

I can't speak for Paulo Santos (owner of airnav.com) but navaid.com does
have *some* Canadian data, mostly because of the Digital Aeronautical
Flight Information File (DAFIF) (which is going away in October, by the
way), and partly because of the generosity of some of my users.

I once spent some time begging NavCanada to release the data, and they
said they'd need their lawyer to draw up a legal indemnity, and I said go
ahead, I'd sign it. So then they said the lawyer was too busy to draw it
up or review it, and when I said I'd pay their expenses to get it drawn
up, they stopped answering my email.

Real computer scientists despise the idea of actual hardware. Hardware
has limitations, software doesn't. It's a real shame that Turing
machines are so poor at I/O.
