Oh my god Jonas this video was amazing!!! The sound, the lighing, the shade of the plane, the left turn and the view of the runway, the sea and the sky!!! Completely liked it, I'm adding it to my fav. list!
You mean winglet? Or the little ∞ shaped thing? This little thing is designed to instal escape ropes during emergency landing on water. Check out Capitan Joe channel on YT, he explains such things. Cheers
