When the plane crashed in a Pennsylvania field on September 11, it was 20 minutes flying time from the nation's capital. On the morning of September 11, 2001, 46 minutes into United Airlines Flight 93, a nonstop flight from Newark, New Jersey to San Francisco, four hijackers took control of the Boeing 757-222. It was around 9:30 a.m., and already that morning, two hijacked planes had shockingly crashed into the World Trade Center in New York City. In less than 10 minutes, another plane would plow into the Pentagon in Washington, D.C. But what of Flight 93? What is known about its intended target?
