But the airship went on, so to speak, again and again to climb. This type of aircraft has those qualities that distinguish it from other aircraft. Our task is not included arguments about the technical aspects or a story about the history of managed aeronautics. For this purpose there rather extensive special and popular literature. Given the specifics "of the Agency for Special Studies," and this web resource, we will focus on the ability to carry commercial cargo airship transportation.
Notable weaknesses Any technical system has its own specific limitations and even vices, which impose restrictions on the practical operation of this system. Airships are also no exception. As times so that's vices of its design are "obliged" disasters and the rather long oblivion. The first and most, perhaps, a significant drawback is the use of hydrogen to create aerostatic lift. Hydrogen is highly flammable and, moreover, it is extremely explosive. Because a hydrogen airships were forced to apply a lot of tricks to avoid creating even the slightest spark in the electrical equipment or metal objects in collision. Hydrogen explosion and fire destroyed rapidly developed in 1937, the largest German airship "Graf Hindenburg" after this airship again successfully crossed the Atlantic and landed in the U.S Second vice constructive pre-war dirigibles – substandard materials from which produced the envelope. They are quite perishable and lose their ability retain gas. Airship with a defective shell uncontrollably losing altitude that, especially in limited visibility and bad weather conditions, led to his death.
