RE: 2006 Nats
Actually, mark, the FAI would have killed the bid because of politics or because of a pre-existing bid form a preferred country. They typically only take a quick look at the business case as they know what entry fees should work to host an event.
FYI. Chad's conversion to CAD for entry fees is about 30% too high. a pilot entry fee to the F3A worlds is 400 euro, about 600cad. he may be paying $800 as an entry fee, but some of that would be used to offset manager and helper entry fees.
