The path of United Airlines Flight 93 flew directly over Lambertsville before crashing in a field southeast of the village on September 11, 2001. Witnesses to the low-flying plane in Lambertsville were the last to see it airborne and the first to place 911 calls after its crash.[1] [2] The Flight 93 National Memorial sits to the east of the village, though access to it is from U.S. Route 30 north of Lambertsville.
