Wasn't familiar with Australian school children episode
I agree with the other comment and review that the topics are typically over-played encounters that we've already been over-saturated with on other UFO cable programs.
That being said, a new topic was the episode with the group sigthing by the Australian school children while on recess (in the 1960s). The fact that 30 or 40 years after their encounter, they reunited to share the experience again.
The number of witnesses added a level of credibility that is compelling.
