No, the Blue Angels are not authorized to break the sound barrier during shows. Their fastest speeds during an air show are around 700 MPH, which is just under the speed of sound.
I grew up in Seattle (Mercer Island) and I just have to say the Blues are OK but it's just getting so old. The same show, the same schedule, the same traffic jams........how about the Blues hang at Whidbey Island or McCord and those who REALLY want to see them can. Fox news thinks their breaking a story here!!! LOL
I don't even know why the Blue Angels come to Seattle. Millions of dollars spent on a show that not everybody can see unless they own property there or they're stuck on the highway
