NASA shared their success of testing a pad abort system today. Being that it is an abort system, you DON'T want to use it. Basically it propels the crew module away from the rocket so that they can escape a malfunctioning rocket.
Here's the video of the test. The whole flight lasts only 135 seconds and the top altitude is about 1.2 miles high.
I appreciate that NASA also shares their mistakes with us too. Back in 2008, I posted the video of Spacewalker Heide Stefanyshyn-Piper's mistake.
