show effects without causes, actions without actors, verbs without subjects, and nouns without predicates. The branding with 3 logos on every slide (the title slide has 4 logos) is unprofessional, pitchy, turfy. Are we doing engineering analysis or marketing here? Some 20% of the space of every slide (already a a very low resolution display method) is devoted to branding and to the boxed-in awkward and repetitive slide titles. It is as if each and every slide has to remind the viewer what the presentation is about. So the top 20% of every slide is something to skip, perhaps putting some viewers in the mode of skipping and sliding through the rest of the slide. It is as if the top of every slide announces "nothing important here, you've seen it all many times before." In several slides, the visually most active materials are the cross-hatched exploding 3D arrows linking the external tank to the magnified areas. Why are the arrows pointing anyway? It's just a simple linking line. The idea here of close contextualized imaging of the problem areas is a very good one, but the badly-drawn giant blue arrows are silly, and result in making the dequantified images of the foam problem areas too small. The typography is poor, with odd hierarchies (underlined bold italic in parentheses at one point). Is "O2" the proper way for NASA contractors and NASA to write the oxygen molecule (even wikipedia uses a subscript)? Does the slide designer know how to write
