A video in two parts. In the first, a planespotter films a Boeing 747 as it leaves Schiphol with no human passengers. Tracking its movement by intercepting radio frequencies and his own knowledge of the flight path. A final 747 flight, as the aircraft becomes obsolete and KLM retires the plane that defined the early jet age. In the second, a carillonneur rehearses within an empty building. Its bells ring out across the closed offices in Amsterdam Zuidas. Incorporating a musical cipher provided by the artist; a carrier of an encrypted message, transferred through the physical striking of bronze bells.
