Yes I’m into rockets, but anyway, here.....Awesome sound! riding along strapped to a booster you are, plunging into the space above. Pay attention to the speed of sound, 750+ and watch the vapor cloud suddenly disappear. The splash down is also reappy cool. Something else on the way down...is the puffs of black smoke off the booster end. Thats a collection of solid rocket motors ignited to keep the attitude at an angle, so it scrubs off speed. Pretty awesome stuff.
