Shytorque, I have seen a similar thing happen on the S Island.
A pilot refuelled a 206 at idle, then the he entered the offfice for 10 to 15 minutes, leaving the aircraft at idle with 20 + heli-hikers around the idling craft. There was an inbound 350 in a hot 1/4 mile final when our 206 pilot ran to the aircraft, jumped in, increased throttle to 100% and immediatley climbed 100' vertical, big nose-over and departed the scene as the 350 was landing beside him.
The company in question had a wrecked 206 in the hangar, and another old 206 wreck clearly visible to the public in a rear shed off of the parking area......????????
I think that they may have another very soon....
