Something is rotten in the state of Denmark
I like that expression
We have one similar here in USA........i smell a rat
Check this out:
You get to your bar at the anchor and put the CL in your harness hook...
....while kite sits pretty on wingtip
Next without touching the bar and keeping the trim line fully depowered like it was....
..... i walk upwind 10..20..30 degrees...keeping front line tension by stepping also back very little
Guess what happens as the inside of kite fills in with wind....it lifts off the ground....
...without any bar input
Kite is anchored with perfect technique
Bar is fully out....trim line all the way in...kite is sitting pretty and stable on wingtip
Next there is a slight 3-5 knot gust and windshift of 30 degrees that fills the kite with wind
Guess what happens too....the kite will also lift off the ground while anchored
So what makes the kite lift off is kiter positioning or wind changing direction...both will do for lift
Agreed we do not know what brand/style kite his 12 m2 was
And we were not there to make sure his technique was precise and perfect
What we do know is the wind direction was sideshore...
....and from experience i know that more often than none that direction is shifty and a bit gusty
So his wind went likely suddenly side side off with a puff to lift his kite up
We can all come out smelling like roses (USA expression)....
..... if we are consistent.... precise.... and disciplined during all launches
