Me either--the controlled release of so much energy can never become truly routine. This video (see: http://spaceflightnow.com/2017/09/0...37b-spaceplane/ ), taken from the press site, provides the odd contrasts between what is seen and heard. The launch begins in silence, but the flame is as bright as the Sun, and the sound--when it arrives several seconds after the vehicle is already well underway--is so overpowering and all-pervasive that covering one's ears makes no noticeable difference. Those extremes aren't conveyed by this video, but one aspect is--how the roar fades away into silence, while the vehicle is still visible (in person, it's a ringing silence, after one's eardrums have undergone such an acoustic assault, but the almost-eerie audio contrast is still there in the video).
