During the invasions of Norway and Denmark in Operation Weserübung, the Luftwaffe dropped paratroopers on several locations. In Denmark, a small unit dropped on the Masnedøfort on the small island of Masnedø to seize the Storstrøm Bridge linking the islands of Falster and Zealand. A paratroop detachment also dropped at the airfield of Aalborg which was crucial for the Luftwaffe for operations over Norway. In Norway, a company of paratroopers dropped at Oslo's undefended airstrip. Over the course of the morning and early afternoon of April 9, 1940, the Germans flew in sufficient reinforcements to move into the capital in the afternoon, but by that time the Norwegian government had fled.
