The deluge system produces a mixture of water and air. That is necessary for the acoustic deadening effect. Once upon a time, there was a thing called Orion, which was supposed to be a big heavy shield that would be propelled into space by setting off atomic bombs on one side of it. Lots and lots of bombs. At some point people thought they could make a shield good enough. What SpaceX puts in now is going to be the closest we have come to Orion, just upside down. --0000000000008c276105fa30b1f1 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
