In the Pavel Hlava video, the camera lens
is originally (#1) close on the South Tower. Then
the camera tilts down (#2). It tilts up. Then the operator zooms-out. Two
seconds later the plane arrives (#3).
The camera angle is strikingly similiar to CNN's famous footage which
was broadcast repeatedly on 9/11/01. In both the camera is looking up
at the South tower from the southeast side. We see UA 175
enter from the left and strike the south wall of the South tower.
