Funny how, with all the high tech, they set them off by basically throwing a match at them.

    1. Who knows.
      Maybe the Mars thing will motivate us to get back to space on our own.

  2. The engines actually have internal igniters, the sparks (from an abrasive wheel and steel pin) and flame are to make sure they light up. Any collection of unburnt fuel could blow the rocket straight off the pad!
