I would rather like to have a discussion about what people think of kite companies having a liability insurance, but guess ..not.
Not an expert but don´t think a scale up bridle would just translate into an over-sheeted kite. Even if the line lengths are corrected I´m thinking about how the distance between the tow point and the aerodynamic center will be outside the intended design, as such all the acting moments and consequently ´how´ the kite will fly.
In the end I very much doubt that I would be able to identify a messed up bridle if I am given half an hour to fly a kite I got no experience with, in particular if my test trial is to fly the damn thing in a (lower than) low wind condition.
I doubt that 99% of the riders I know or the people who write here would be able to identify the messed up bridle in the same circumstances.
Also the given ´keep it safe´ suggestion to spend half an hour flying and tuning a brand new kite in land does not make much sense to me, as there is not much tuning outside the flying wind envelop and powered kites are better flown in the water.
Glad the dude is fine.
