Ten minutes? Sorry that cannot be correct in any universe that I am aware of. Not even for an A380 on a dead calm day. And as others have said, a Caravan might briefly create a problem for an ultralight but never for a Lance.
I cannot conjure up any rational scenario for the flight path in the photos other than mechanical failure or breakage of some sort. If a strong rotor hit the aircraft just after takeoff and the aircraft started to roll right as it pitched up, control input was made to roll left to correct it but then for some reason remained locked, unable to be reversed, the aircraft would continue to roll left as shown. Even if the controls were returned to neutral, if the left wing was approaching a stall at the published 60 kts, with the bank angle already in play the right wing could potentially continue to roll the plane to the left as shown.
But I'm not a Lance driver so I would defer to anyone with more knowledge who finds holes in my theorising.
