Frank makes a good point. Flow Illustrator is only in 2-D cross-section. A vehicle moves through the air in 3-D. Do we assume that the sides of this cap are solid like Bondo's hinged aerocap, with flat plates instead of a hatch? I sure would like to see someone build and test a version of this idea.
