Note: Every tag is unique. Depending on the plane, tags may vary in haptics, thickness of material and colour. Small irregularities tell of a plane’s long history and convey the feeling of its glory days above the clouds.

McDonnell Douglas DC-9 is a twin-engine, single-aisle jet airliner by US manufacturer Douglas Aircraft company. It was designed for frequent, short flights.The two engines at the hull are aerodynamically advantageous and improve handling of the plane in case of engine failure. The DC-9 30 is almost 4.5m longer than the original design and can carry up to 139 passengers. The elongated wings and innovative slat and flap system make take-off and landing on short runways possible.
