LZ 127 Graf Zeppelin was a German-built and operated, passenger-carrying, hydrogen-filled, rigid airship which operated commercially from 1928-37. It was named after Ferdinand von Zeppelin, who was a count (Graf) in the German nobility. The airship made its first long distance journey in 1928 with a crossing of the Atlantic to the US. Later flights included its round-the-world tour in 1929, the Europe-Pan American flight in 1930, a polar expedition in 1931, two round trips to the Middle East, and a variety of other flights around Europe. The Graf was withdrawn from active service on the day after the loss of the Hindenburg in 1937. During its career the Graf Zeppelin flew more than 1,056,000 miles becoming the first aircraft in history to fly over a million miles.The Graf was scrapped in 1940. The Giza Necropolis (pyramids of Giza) is an archeological site on the Giza Plateau, on the outskirts of Cairo, Egypt. It is by far the oldest of the ancient Wonders and the only one still in existence.
