What I'd like to know is, who are we pilots obligated to show our registration number to if asked? The FAA? Of course, but I've never seen an FAA guy in the field. How about the local Police dept? I would assume so, but not sure since it's not their registration number. Will the local police have direct access to the FAA database? How about my neighbor, or any stranger that walks up and asks me to prove I'm registered? I'm I obligated? I hope not. Will the public have access to the database? I hope not. Will the FAA accommodate lost drones, providing anyone with the contact information for a drone registration #? That would seem inappropriate to provide personal information to anyone that calls the FAA with a registration number. But at the same time I'd like to get my drone back if it's lost. How will that work?
