Beth　said；　〃It's　like　being　in　an　oil　refinery。〃　She　shone　her　light　on　one　steel　beam。　Stenciled　was　〃AVR…09。〃　All　the　stenciling　was　in　English。

〃Most　of　what　you　see　is　structural；〃　Barnes　said。　〃Cross…stress　bracing　for　the　outer　hull。　Gives　tremendous　support　along　all　axes。　The　ship　is　very　ruggedly　built；　as　we　suspected。　Designed　to　take　extraordinary　stresses。　There's　probably　another　hull　further　in。〃　Norman　was　reminded　that　Barnes　had　once　been　an　aeronautical　engineer。
