The ATC-tower at Stockholm Arlanda provides a good view over the airport and nearby areas. Terminal 4, built in the 1980s,  is seen at the front, with the city of Märsta featured in the background. A Finnair A321 has just arrived at runway 19R. A mix of MD-80, Boeing 737 next generation and Dash 8 are a regular sight at this domestic terminal, mainly used by Scandinavian Airlines.
