Definitely a Squirrel, and yes I agree with General Lee - looks like a dose of ground resonance to me. Not usually encoun tered with machine that has skids - more often on a wheeled machine. For those who aren't up on these things GR can occur when the weight of the machine is split between the blades and the landing gear, and an irretrievable o scillation occurs. The pilot probably did not have the collective lever all the way down. 

Saw the video on television news...Looks to me like a sloppy pilot set it down the wrong way and hit "ground resonance" (look it up)...

Wow 'Kermit Frazier'.  Nice to see you don't let facts get in the way of a good story, I especially love your knowledge of aircraft.. Fact: This is NOT a "Huey" Bell Iroquois. Fact:&nbs p;This IS a Squirrel (Eurocopter ES350). Even if it was a Iroquois, they are some of the most reliable choppers still flying around today, and squirrels are a well built, popular chopper.  Yes, maybe there was maintenace issues, but it has nothing to do with the make and model..  well done on your witch hunt..
