At the Flight 93 crash site, an excavator digs through the soil where the plane impacted. [St. Anthony Messenger, 9/6/2006] It takes scoops of dirt and dumps them into a high-lift bucket, which takes the dirt to a flagged off area and slowly dumps it there. A couple of FBI men then search through it with their hands. Occasionally, the excavator digs into a “hot spot” in the earth, causing a small fire. The Shanksville Volunteer Fire Department has to be called in to extinguish these fires. [Kashurba, 2002, pp. 56 and 128] The cause of the ‘hot spots’ is unknown.
