Brad, if the plane conforms to Part 103 and the public airport doesn't have a control tower and it's daylight hours and operation is not within Class A, Class B, Class C, or Class D airspace or within the lateral boundaries of the surface area of Class E airspace designated for an airport, the answer to the first question is yes; you can roll up to the airport with plane in tow, unload and fly. There are no airworthiness certificates for Part 103 ultralights and no pilot certification is required, so I doubt the airport manager could demand to see them.Can you just roll up to any public airport with plane in tow, unload and fly? Does the airport manager have the authority to tell you no? Does the manager have the authority to ask for airworthiness docs and pilot certs?
If that last flight when the runway lights were broken happened after twilight, there might be a case to take action against the pilot for flying at night and for damage to the lights.
You're a stone's throw from 3S8; have you heard any more details about the incident in the local news, like was it an ultralight?
