根据材料，回答问题。The Olympic Flame from the ancient games was reintroduced during the 1928 Olympic Games.An employee of the Electric Utility of Amsterdam, lit the first Olympic flame in the Marathon Tower of the Olympic Stadium in Amsterdam.
The modern practice of moving the Olympic Flame via a relay system from Olympia to the Olympic venue began with the 1936 Summer Olympics in Berlin, Germany.
The relay, captured in Leni Riefenstahl's film--Olympia, was part of the Nazi propaganda machine's attempt to add myth and mystique to Adolf Hitler's regime. Hitler saw the link with the ancient Games as the perfect way to illustrate his belief that classical Greece was an Aryan forerunner of the modern German Reich.
Although most of the time the torch with the Olympic Flame is still carried by runners, it has been transported in many different ways. The fire traveled by boat in 1948 to cross the English Channel, and it was first transported by airplane in 1952, when the fire traveled to Helsinki. All carriers in the torch relay to Stockholm, where these events were held instead, traveled on horseback.
Remarkable means of transportation were used in 1976, when the flame was transformed to a radio signal. From Athens, this signal was transmitted by satellite to Canada, where it was received and used to trigger a laser beam to re-light the flame. In 2000, the torch was carried under water by divers near the Great Barrier Reef. Other unique means of transportation include a Native American canoe, a camel, and Concorde. In 2004, the first global torch relay was undertaken, a journey that lasted 78 days. The Olympic flame covered a distance of more than 78,000 km in the hands of some 11,300 torchbearers, traveling to Africa and South America for the first time, visiting all previous Olympic cities and finally returning to Athens for the 2004 Summer Olympics.
Another means of catching attention has been the lighting of the fire in the stadium. At the 1992 Barcelona Games, Paralympic archer Antonio Rebollo shot a burning arrow over the cauldron (大汽锅)from a platform at the opposite end of the stadium. Two years later, the Olympic fire was brought into the stadium of Lillehammer by a ski jumper.
