The Blue Angels is the United States Navy's flight demonstration squadron, with aviators from the Navy and Marines. The Blue Angels team was formed in 1946, making it the second oldest formal flying aerobatic team (under the same name) in the world, after the French Patrouille de France formed in 1931.
The Blue Angels' six demonstration pilots currently fly the McDonnell Douglas F/A-18 Hornet.
I believe that is a kite with a dummy hanging from it. Not sure though :)
