She spied a familiar logo on several of the nearer buildings and realized it was all NASA property. The Houston of "Houston, we have a problem." A little more altitude gave her the perspective to delineate a border fence, guarded by gates where it was pierced by roads, as well as other kinds of defenses that had been heaped up to protect vulnerable parts of the complex from floodwater. But the swarm didn’t go in that direction. Instead it followed an adjacent road to a commercial development that was as close to the Johnson Space Center as it could get without encroaching on government property. Logos on some of the buildings, and signs planted near street entrances, were suggestive of aerospace.
