Dude, you are completely clueless. The only Restricted Areas are Military. Other areas can be designated as a TFR (Temporary Flight Restriction) which has its own guidelines based on the need. Some are completely restricted like one for POTUS. (President of the United States) or a minor restriction for a forrest fire or NASCAR race. There are a couple of more areas where special rules are in place, such as the Grand Canyon, certain Wilderness Areas etc.. So, the helicopter was NOT in a restricted area. Get it????

Secondly, I've already explained that 75 feet over the ground is not in itself dangerous. Have you ever been in a helicopter or have any idea what you are talking about? Never mind, you've already answered that.

Regarding your NTSB friend, do you want to provide his name for us? He does not have enough facts to make such a statement.

AGAIN, the helicopter is possibly not without some issue here. But, the model must always yield to the manned aircraft. ALWAYS, NO EXCEPTIONS. Now lets move on. Give this a rest, it is done and horse is getting beat over and over again.
