America has been looking back on some of the major milestones of 1969 this year. 50 years on, the impact of the moon landing in July and the Woodstock festival in August is still being felt. The three days of peace and music in upstate New York could have been a disaster, with an unready site, untested promoters, and nearly half a million people. Instead, it came and went without any major emergencies — and left some landmark music in its wake.
Woodstock is the subject of a new American Experience episode that debuts on PBS August 6. Jamila Ephron is the co-director of "Woodstock: Three Days That Defined A Generation," which premiered at the Tribeca Film Festival in the spring.
