Today is three years after the September 11, 2001. Two planes crashed into WTC towers in N.Y., third plane slammed into Pentagon and fourth went down in Shanksville, Pensylvania. About 3000 people were killed that day. The moments of silence were held at 8:46am (first plane), 9:03am (second plane), 9:59am (south tower collapsed), 10:29am (north tower collapsed). The family members of September 11 victims read the names of all the people killed in that attack.
