 The current model of the hyperloop focuses on some of the primary sub-systems that operate within the pod. However, there is much more
 analysis that needs to be done to build a complete hyperloop model.

+Some alternate configurations could possibly considered as well. Although the length of the capsule would grow by a factor of 2, it

 In addition, some investigations need to be made into the lower speed operation of the pod. It's possible that splitting the compression
 system into two independent paths would be beneficial, if the bearings require a relatively constant mass flow rate and pressure, because it
 would allow a more flexible operation of what is currently the first stage compressor.

+The passenger pod is, from a structural perspective, a pressure vessel experiencing a fairly high pressure ratio of around 1000. The original
 design concept calls for a non-circular pressure vessel which raises some structural design issues. It's possible to design an effective
 structure using modern aircraft grade composites technologies, but it's possible that a round cross section could allow for a more
 traditional construction and reduce costs. Structural models considering composites and metallic construction are needed.

 \subsection{Route Optimization} \label{app:route}
 The current mission analysis takes the velocity profile in the original proposal as a given. We normalize this profile in both time and velocity,
-then integrate it. This gives a speed factor of about .8. So for any given maximum velocity, the average velocity would be about 80% of it.
+then integrate it. As modeled, the average velocity would be about 80\% of the calculated max speed.
 
 While this simple method provides some basic dependence of travel time on overall speed and tube length it is not really sufficient. A more
 advanced analysis needs to be constructed which accounts for actual passenger G-load constraints and can derive an optimal route and
 speed profile for a given design.

-To use the hyperloop model, you want to run the file src\\hyperloop\\hyperloop\_sim.py in the hyperloop repository. If you have already done that and you're ready to go, then you need not read any farther in this section. We're going to explain whats going on in this file next.
+To use the hyperloop model, run the file src\\hyperloop\\hyperloop\_sim.py in the hyperloop repository.

 The file starts out with some library imports and the i/o definition of the HyperloopPod assembly.
