2. The Hindenburg • The Hindenburg was a huge gamble in a long line of gambles for the Zeppelin Company. She still holds the record as the largest aircraft ever to fly but, as majestic and awe-inspiring as she was, the Hindenburg was meant to be only the first of a fleet. History dictated that she was to be the first of only two. • The Hindenburg was a marvel of zeppelin design. Her sheer size was truly an engineering masterpiece. For years builders of dirigibles, including the Zeppelin Company, had simply stretched the hulls of their airships to accommodate more lifting gas. The British built R101 was actually cut in half and had a whole extra section added to accommodate an additional gas bag to increase its poor lift and the famous Graf Zeppelin was in fact, little more than a stretched version of the LZ126, the Los Angeles. The Zeppelin Company decided that with this new zeppelin, they would increase gas volume by not only making her the longest they could, but also by radically increasing her girth. Where the Graf Zeppelin was an impressive 100 feet in diameter, the Hindenburg would measured in at 135 feet and 1 inch. Even though an increase of a little over 35 feet doesn't sound like so much, remember that these monstrous ships needed hangers to protect them from the elements and when the Hindenburg was being built in her new construction shed, she was wedged in as tight as possible! With her massive diameter and her impressive length, the Hindenburg would carry a gas volume of 7,062,000 cubic feet. This volume, when filled with hydrogen, would produce an astounding 242.2 tons of gross lift. The useful lift (the lift left after you subtract the weight of the structure from the gross lift) was still 112.1 tons. An astounding weight even by today's standards but mind-blowing in the 1930's. At this point in world aviation, airplanes could fly only short distances with constant refueling and as little weight as possible.

3. The H-Bomb • hydrogen bomb or H-bomb,weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy. Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy. Because extremely high temperatures are required in order to initiate fusion reactions, the hydrogen bomb is also known as a thermonuclear bomb.
