What drove a company of American soldiers—ordinary young men from around the country—to commit the worst atrocity in American military history? Were they "just following orders" as some later declared? Or, did they break under the pressure of a vicious war in which the line between enemy soldier and civilian had been intentionally blurred? American Experience focuses on the 1968 My Lai massacre, its subsequent cover-up, and the heroic efforts of the soldiers who broke ranks to try to halt the atrocities, and then bring them to light.

On November 17, 1978, Congressman Leo Ryan traveled to Guyana to investigate the concerns of constituents.

Within 2 days, Ryan, Jones and over 900 Jonestown settlers were dead; casualties of a mass murder-suicide. American Experience goes beyond the headlines to provide a revealing portrait of Jones and The Peoples Temple.

This session assesses the power of the Apollo imagery in modern society. NASM Senior Curator Roger Launius will discuss the rise of six iconic images and how they have been used over time while Museum Specialist Jennifer Levasseur will explore the fascinating history of the cameras used to capture these images.
