Moments of Remembrance

The piper will play at the moments of impact — 8:46 a.m., 9:03 a.m., 9:37 a.m., and 10:03 a.m. — marking the times when the four hijacked airliners crashed into the World Trade Center towers, the Pentagon, and a field in Shanksville, Pa. The Memorial Tree was planted in memory of the seven alumni who perished that day.
