Lex, nice interview - but I feel kind of sad for Sara on the topic of ET's/UFO's - she's spending her time looking for something she's convinced herself doesn't exist.  She should start looking at evidence that shines a new light on her convictions - that academia might not know everything there is to know about the universe.  I say this because my background is mechanical engineering &amp; meteorology - I've had over 20 sightings now - this phenomenon is way beyond our current understanding of physics.  This realization shouldn't be frightening, it should be welcoming.
