This is not a new problem. I remember 25 years ago an article in Rotor &
Wing about a local group of helicopter pilots somewhere (news gathering,
police, air evac) sitting down and formalizing the priorities,
altitudes, direction of orbit, etc. for arrival on the scene of whatever
they were covering. To the best of my knowledge, they were the only ones
who did it. I ask one of the local news pilots where I live if the local
pilots were going to get together and for such a pact. His response was
that his station wouldn't agree to anything like that.

Seems to be some hysteria about the recent collision in Phoenix. It
was a pure and simple see and avoid problem. Doesn't matter who had
right of way, if they were adhering to FAR's or not, bottom line is
two helicopters tried to inhabit the same airspace with the fatal
results of four dead simply to cover a news story that was not all
that newsworthy.
SEE AND AVOID.
Someone screwed up. Let the lawsuits begin....................
