Liftoff of the twenty fifth space shuttle mission, and it has cleared the tower. Control good roll program confirmed. Challenger now heading down range. Engines beginning throttling down now at 94%. Normal throttles, for most of the flight, at 94%.
We'll throttle down to 65 shortly. Engines at 65%. Three engines running normally. Three good fuel cells, three good APUs. Velocity, 2,257 feet per second. Altitude, 4.3 nautical miles. Downrange distance, three nautical miles. The twenty fifth space shuttle mission is now on the way after many delays. One minute fifteen seconds. Velocity, 2,900 feet per second. Altitude, nine nautical miles. Downrange distance, seven nautical miles. Looks like a couple of the solid rocket boosters blew away from the side of the shuttle in an explosion. My controllers here looking very carefully at the situation. Obviously, a major malfunction.
