What I find interesting is the rotor disc doesn't tilt. Even as the aircraft lifts tail first. You'd think they would have at least shifted the cyclic aft when the tail came up. But I don't think their intention was to fly. The aircraft starts to slide forward on the skids then the tail lifts rather uncoordinated and it flops over. My SWAG at the moment is either an unintentional control movement in the cockpit or a disconnected control tube at some point like at the mixing bellcrank or on the deck where the cockpit crew was simply along for the ride.

Clearly, this 206 was out of control from the moment the skids left the earth. I'm gonna go out on a limb here and chalk it up to the "pilot left the cyclic friction on" cause. A lot of 206 pilots really like to crank the cyclic friction on while doing the runup for some reason. I've seen people forget it. "But you'd notice!" Would you? Maybe not. Depends on who did the runup and who was doing the takeoff.

It is curious that the first person out of the wreckage appears to be the guy who was sitting in the right-hand (i.e. PIC) seat. The *second* guy who gets out appears to be seated on the left-hand side and - strangely - he is wearing a helmet. Now, was *he* the PIC? And did he let the other guy sit right-seat and make the takeoff? I've seen accidents caused my weirder stuff.

How does cyclic friction induce a yaw?

That leap off the ground is so abnormal and no indication of any cyclic inputs at all makes me think the only control that moved was the collective so as a pure surmise I'd suggest it is just what might happen if someone accidentally snagged the collective.

Torque creates Yaw....perhaps one of the occupants abruptly twisted the Friction Control and thus caused the helicopter to rotate around the cyclic stick? Asking for a friend!

No, the copilot rolled his eyes and the Coriolis Effect made the skids dig in.

😂😀😁 very funny Charlie

Whatever happened, I'm surprised pilots can still find new ways to wreck helicopters.
