Low angle (who's looking?) showing Jacob behind the glass. Blinking his eyes in code, hoping that the shuttle people will look out, look at him, see the peculiar pattern of blink blink blink behind his veil and glasses, and make proper course corrections based on this new and accurate information. Jacob further encodes the story he sends them by wiggling his eyes back and forth a bit. Sounds simple, but the variables pile up pretty quickly.     They flattened the sands, and built a room for me on stilts, so that I could be in the air when the shuttle returned.
