Late 808

T-minus 90 seconds and counting
Sound suppression water system now being armed for release
We have three main engines ready for ignition
Space shuttle now on internal power
Liquid oxygen and liquid hydrogen fill and draining valves are closed
Saw the rocket booster flight data recorders are activated
30 seconds into the flight, Atlanta’s almost two miles in altitude
Almost six miles downrange from the Kennedy Space Center already, traveling 500 miles an hour
One minute thirty seconds into the flight, fifteen miles downrange, traveling almost 2000 miles an hour
Three good auxiliary power units, three good fuel cells, three good main engines
Ten seconds away from summit-rocket booster separation
Nine, eight, seven, six, five—three, two, one, zero

“At 5:49 a.m. EDT (9:49 UTC), the SpaceX Crew Dragon Endeavour spacecraft and Falcon 9 rocket will lift off from NASA’s Kennedy Space Center in Florida. Shane Kimbrough and Megan McArthur of NASA, Thomas Pesquet of the European Space Agency, and Akihiko Hoshide of the Japan Aerospace Exploration Agency will join the station’s crew, for a mission of approximately six months. This will be the first launch through our Commercial Crew Program to fly two international partner astronauts, and the first reuse of a Crew Dragon spacecraft and Falcon 9 rocket for a crew mission.” -NASA
