Stage 0

This stage is used for adjusting the height of the base of the pyramid, with the most important part being that the stage must end with zero velocity.

As shown above, stage 0 goes deep underground* and slows to a stop over 2.5 seconds, creating the platform for stages 1 and 5 to launch from.

To see the full pattern of the later stages, you can change the launch speed to 0 and the thrust forward to -33.0 f/s^2 to platform at ground level.

* fireworks flying underground is not realistic, but it works in ATITD and helps to overcome the limited number of stages.

Stages 1 - 4

These stages form the top of the pyramid.

Stage 1 launches from the stage 0 platform and sets the height of the top of the pyramid.

Stage 2 is a hovering platform at the tip of the pyramid that is used to launch the sides.

Stage 3 adds downward momentum which combined with Stage 4 will create the angled sides. The 45 deg roll aims the sides toward the corners.

Stage 4 adds outward momemtum and the ring provides for the 4 edges. Since the momentum from stage 3 and 4 combine to make the 'forward' direction a 45 degree downward slope, stage 4 uses both forward and pitch up thrust to combine to form a hovering thrust.

Stages 5 - 9

These stages form teh bottom of the pyramid.

Stage 5 launches from the stage 0 platform and sets the height of the bottom of the pyramid, it combines with stage 6 and gravity to allow stage 7 to become a platform.

Stage 6 uses a ring to create the seeds for the 4 bottom edges. The launch speed determines the size of the base. The combined duration of stage 5 and stage 6 need to = the launch speed of stage 5 / 33.0 (so that stage 7 will be moving neither up nor down).

Stage 7 and 8 are the hovering platform for the sides. Stage 7 counters the outward momentum from stage 6's ring and then hovers in place for a bit to give the top time to get ready. Stage 8 rotates 90 degress (so the ring will work) and provides the platform for the repeated side launches.

Stage 9 draws the sides by launching rockets fromt the middle of each side towards the two adjacent corners.
