Ciao Planko!
You are not alone.
Kept thinking I was going to see the thing 'fall over' at any moment.
His 'driving skills' put him in the 1000 hour or less category in my view.
I'm all for a wee bit of fun but .. done in the right way (adequate ground clearance, at a safe distance from spectators and flying within one's abilities) but .. the words 'idiotic' and 'unnecessary' sprung to mind while watching that. I suppose the vodka from the previous night's session may not have completely worn off!
My hope is that he's got it out of his system, will be thankful that he didn't totally screw up his moment of madness and will think twice before endangering himself or others in the times ahead .. there are enough inherent risks in most standard flying operations as it is.
