During the panning shot as the abductees are leaving the group therapy session, a boom mic can be seen and is then withdrawn from the shot.
(at around 1h 55 mins) While the group are sat for dinner, bottom of the boom is seen just off center at the top of the screen. At 54s it bounces down and then back up out of shot at 57s.
