This is the best interactive demo I've seen so far. Thanks NASA! They even let you view the eclipse from the Moon's perspective

Until you realize NASA is a program to control the masses. The earth is not a globe, just look at the United Nations logo and the only treatry where all countries are in agreement. To stay away from Antarctica which is the outer edge of the planet... Soon I believe someone will make a name for him self more that Christopher Columbus when the truth is revealed... Go to the beach in Florida and you can see mainland Mexico with a telescope, there is no circumference...
