You can also watch it on Icelandair's Facebook page & don't forget to give them a like (love) because they were pretty awesome to stream it for us. Like and follow them here: https://www.facebook.com/Icelandair/videos/10153790502411557/
note: it was a little dark so i just brightened the video here so we could see their faces better :)
