A pilot landed near here after making a landing on a farm to market highway, (something with the sump leaking), and then flew away to land at the next airport.
The highway patrol wanted to talk with him and look at his documents -- and he wasn't carrying anything. No medical, no PPL license, no logbook, but the plane did have the registration and airworthiness. (And he had ID that satisfied the police he was who he said he was.)
He told the police he was very tired, so they took him to a nearby hotel. While he slept they logged onto the FAA site, found everything in order. Got him the next morning, took him back to the airport, wished him a safe flight and away he went.
I was there when he left that morning, heard the police wish him a safe flight, and he took off. The rest of the story I heard from the FBO operator.
I think nowadays the info is readily available to all the government agencies, so they can check about as quick as we can hand over the documents. Also, for a tailwheel endorsement or other endorsement, who checks except when there is an incident or accident?
