From Phil's blog today
Why did it take so long to step onto the moon after they landed? That's over 6 hours between the landing and climbing down.On July 20, 1969, at 20:17:40 GMT, human beings landed on an alien world. That was the moment that the Eagle lander touched down on the surface of the Moon, 40 years ago today. Nearly five hours later, at 02:56:15 GMT on July 21, Neil Armstrong placed his boot in the lunar regolith, planting it firmly into history as well.
