The Dutch naval vessel HDMS Ejnar Mikkelsen patrols the North Sea between Greenland and Norwegian waters conducting search-and-rescue operations in those cold, unpredictable waters—often requiring its helicopter pilots to take off in extremely choppy waters. The result is something that might give you motion sickness just from watching it on your computer. Indeed, whoever was piloting this Lynx helicopter in this video deserved a beer and a Dramamine (probably not at the same time) after they landed.
