"We see this as a serious incident," said Director of Avinor Bergen Airport Aslak Sverdrup.
More than two weeks after the incident, the police are still left without suspects in the case. Oddbjørn Dyrdal of the local police acknowledged that such cases are difficult to investigate, and has recommended the registration of all drone owners, claiming that it would make the investigators' job easier.
"Nowadays, drones can be purchased in all possible varieties, and differ in term of quality and range. I think the licensing of such drones should be made mandatory," Dyrdal told Norwegian national broadcaster NRK.
Until now, the CAA has not deemed it necessary to make drone license mandatory, but forecasts such measures will be necessary in the long term.
"Controllable model aircraft have been used successfully for very many years, but now this has become a problem," said Schaug-Pettersen in the CAA.
The CAA is not surprised by developments. "Some of these events risk resulting in considerable damage," Eirik Svare, senior engineer at the CAA told NRK.
The CAA has an online course that they recommend for all drone users. For those running drones that weigh more than 2.5 kg, the course is compulsory. Starting from January of next year, a mandatory exam will follow the online courses.
