The Police Authority and the Defence Forces carried out a joint exercise with helicopters in the Stockholm area on Wednesday.
The helicopters could be heard and seen in the air in both Stockholm's eastern archipelago and Stockholm's inner city, among other things, an helicopter of the model Blackhawk UH-60M practiced by the parliament house's roof.
We never take vacation but we practice continuously throughout the year, says the Defence Forces' press secretary, Vendela Kirsch to Expressen.
