Aha opinion ping pong - with out personal experience of the young lass - a lot of this is too pre-judged. There are 3 opinions presented in this thread I read and automatically respect - both side of the opinion divide.
I reckon most people's gut feeling is that she is under done on the preparation side - fatally?? Well some weather conditions out there will be fatal regardless - refer movie clips - but a lot of ok weather occurs through these areas which does not make a You Tube clip. I worked 3+ years at sea and mostly is was not really wild - but the few times which were were out there - (pre UTube!!).
Would I stop her if I had the emperor's thumb - no.
Why? - There is one of her trying in this country.
Since I heard of the trip - without trying to I have also heard of a kid fatally bashed to death in an "Accident" in a local school yard - and at least three kids younger than Jessica dead around a tree / lamppost - in car crashes - a suicide - etc.. this information is sourced locally - so on a national basis there would be more young deaths through a range of courses - most through far more shallow less prepared and thought out circumstances..
So if she wants to fly and it fails I as a parent would feel - better to happen trying than the all too common alternatives.
She is not guaranteed to fail - far from it. I will follow her endeavor with interest - I will not be totally gob smacked if she retires after 30+% of the journey - and would still give her the thumbs up for trying.
And on a totally different note - Blood_ H!!! the W/E and wind are coinciding - amazing

- 4U2 I hope
