Reindeer herders use old Norwegian Navy landing craft to ferry some 10,000 reindeer every year to their summer pastures on islands in Troms and Finnmark counties, and Olsen wanted to catch a herd swarming like birds or bees.
"We knew there was going to be some movement inside the corral, and I though out the whole thing in advance," he told Norway's NRK channel of the footage. "I was OK".
Reindeer herder Aslak Anders Gaup said that the reindeer had travelled nearly 300km from Kautokeino.
"The Reindeer have traveled a long road," he said. "So they are tired, and we transport them by boat."
