The Air Force has the Thunderbirds, the Blue Angels are Navy.
Let's not forget Marines too!!
I was a mere boy, and I say the Blue Angels fly at a little flyin in the middle of nowhere - some little 5 hourse town. I was a little boy at the time. I asked them about the being in the Air Force, and they said to me "We are Navy. ANd don't forget it bub!"
I always remember that whenever I hear of the Blue Angels. Too funny.
