A group of Air Force pilots created a group of a cappella songs named in The Stairwell and made quite a performante at America’s Got Talent this year.One of the pilots comes to the stage and begins to play “Some Nights” by Fun. He starts alone, and the rest of the band comes to join for great performance. Performance is based on a wonderful crescendo. They don’t only protect our country but they manage to create something beautiful and unique. Watch the great performance here :
