Closed per the manager, but he went home. Catalina Island.
Local airport, KCGS, College Park, MD, had a curfew at sundown. Owner and manager is the Maryland National Capital Parks, and the Park Police headquarters then was 2 blocks away.
Homecoming football game had a large fly in attendance, and the owner of a 6 seat twin, Beech, I think, partied beyond the curfew, and his hosts brought him and his fellow graduates to the airport. An officer, tasked with seeing there were no violations of curfew noticed headlights on the access road, and drove over to see that no departure occurred. There was a discussion, and the pilot agreed to remain until next day, his host agreed to put them up, and all left the airport.
An hour later, the pilot returned, quickly fired up his engines, taxied to the runway and initiated a departure.
The previous Police officer arrived, drove onto the opposite end of the runway, with siren and lights on, and accelerated down to meet the plane. They met a quarter of the way down the runway, and he claimed it hit his long whip antenna as it passed over him.
Charges and counter charges flew in both directions, but the police request to the FAA for enforcement against the pilots license was an eye opener for the airport owners, and policeman. If there had been damaging contact with the airborne aircraft, the total liability would have been on the police interference with an aircraft in flight. Consider what the result would have been if the plane had been just 3 feet in the air, and solidly impacted the hood and windshield of that police car. After repeated discussions with the FAA, the officer recanted his claim of impact with his antenna.
The Commission posted a ban on police cars on the runway, and posted it at the police station, and airport office.
All the airport could do was issue a lifetime ban on the pilot flying into KCGS, which they did.
Some details may be poorly remembered, but the story was supplied by the MNCP Police Commissioner, a pilot, close friend, and corporate partner. A true inside source.
