Last minute adjustments are made now because chances are you are flying tomorrow morning. This is a very exciting moment because you know that the next time your feet are on this ground that you will not be the same person. Everyone sits in the back, some crack jokes, others look scared to death, but we all have this glossy wonderous look in our eyes.

Once the conditions are right, the plane will nose up 45 degrees and the 2-g pull out begins. At this point all experimentors are seated at their experiments and are pressed into the floor.

This is the point that everyone has dreamt about.
