This blow to local helicopter operators appears to be yet another win for Osama Bin Laden, and the ability of governments to come up with the worst possible reactions to a changed security environment.
My hopes are that you are all able to raise enough of a counter to this that an accomodation may be made to allow you to keep operating and make provision for securing certified operators to keep doing what helicopters do.
Make sure the media know how much revenue you'll lose, how many jobs will be influenced (to include mechanics, etc) and so on.
Raise hell.
Best wishes.
