How do feathers work? See just how the Golden Eagle carries its massive frame through the air in stunning slow motion.

Video Script:: 

we're here with Lloyd buck again he's brought one of his biggest wealth his biggest Raptor yeah Golden Eagle Tilley most powerful avian predator in the UK how BIG's her wingspan 2 meters 2 meters so what we'd love to see is just how bird that big is able to fly and what the feathers are doing [Music] did you really sensitive bird so when you do anything with you and watch us to be calmer less [Music] [Music] [Music] [Music] [Music] [Music] and these are the primaries in today is that what their course the ones that run the I suppose the first thing you notice on that thumb and so you just said it there the Aluna isn't it yeah there's some action of those feathers that give some finite control these are the effectively the remedies it's not what it's called yeah so that's sort of the the wing feathers if you like yes the Latin meaning remedies which means oarsmen which is quite nice so they're literally sitting like always getting the driving force of the flight through and then these tail feathers they're the wreck tri-c's is that right yeah and that translates as helmsman so that's like the directing force I guess over the last minute these ones flaring out here yeah just as she comes in it oh yeah lot right close to our bodies to these two that's weird isn't it you see these ripples look at those all across the wing was this all right yeah so real so striations near these real stripes of and coming through that's the first time anyone's ever filmed her feet he'd be close up come near like that she's got as much crushing power in those feet as a large dog really its mouth Wow this is me I'm in the king Tilly in terms of dimensions were actually pretty similar which is terrifying [Music] look at the primaries last so long how long are they now one of her longest primary feathers it must be you're talking the feathers copy that length fellow was that again sort of just try and get more lift to get more bulk up illegal so she's she's evolved for soaring flight rights just maximizing her surface area to catch as much air coming I don't see how these primaries really bend at the end here yeah on the modern jet liners now they have those little bits that Kathleen to the wake yes I've seen and that's all to do with aerodynamics I think it saves fuel the designer that I believe he's based on studying Eagle flight oh nice one today hey nice one annoyed lesson Rose rounds [Applause] [Music] [Music]
