ahhh yes...gust of wind...funny how that kind of thing happens when you try to have your friend in position to video a "watch this" take off

As soon as the NTSB/FAA sees this video the pilot is done.

Considering this...
1- the pilot did not use the longest part of the lake (screen left),
2- he aimed at the camera for takeoff,
3- and the relatively limp wind sock seen near the end of the video (screen right) will debunk the "gust of wind" statement in the article
