I didn't mean to call anyone ignorant. That green plastic card we carry while flying which says "certificate" on the front has a "signature" block on the back. We all read important legal documents before we sign. Y'all DID sign it, right?
American aviation pioneers refused to accept state licensing because it was too restrictive. They insisted on recognition of international rights as accorded to mariners. So we have certificates to exercise rights, not licenses for limited privileges, and the PIC is called "Captain." The passengers have "tickets".
