{"product_id":"9781455421107","title":"British Airships: Past, Present and Future","description":"First published before the invention of airplanes, this book focuses on lighter-than-air craft. It begins: \"Lighter-than-air craft consist of three distinct types: Airships, which are by far the most important, Free Balloons, and Kite Balloons, which are attached to the ground or to a ship by a cable. They derive their appellation from the fact that when charged with hydrogen, or some other form of gas, they are lighter than the air which they displace. ”","brand":"B\u0026R Samizdat Express","offers":[{"title":"Default Title","offer_id":47155151864048,"sku":"9781455421107","price":0.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781455421107_p0.jpg?v=1763867267","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781455421107","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
