The LZ 130 Graf Zeppelin ΙΙ was the last Zeppelin built in the time between World War 1 and World War 2. Built from the same blueprints as its sister the LZ-129 Hindenburg, in October, 1937, LZ-130 was modified to use helium after the LZ-129 Hindenburg crash, delaying her first flight. Because helium provides less lift than hydrogen, LZ-130’s passenger capacity was reduced from the 72 carried by Hindenburg to just 40.
