The second strike, at 52 seconds after liftoff, knocked the onboard guidance platform offline.
Approximately fifteen seconds after liftoff, the rocket fell back to the ground and exploded.
V is simply the integral under the shock acceleration curve, equivalent to the liftoff velocity of the object undergoing shock loading.
Impact with the ground occurred 30 seconds after liftoff.
At liftoff, these engines will generate a total of 130000 kg of thrust.
For vertical launch of a rocket the initial thrust at liftoff must be more than the weight.
Orbiter mass at liftoff was 247,129 pounds (112,096 kg) including payload.
Four seconds after liftoff, the engine overheated and burned through its gas generator, severing an oxidiser line.
