"The model legislation seeks to regulate a largely unregulated area: the lowest reaches of the National Air Space, or NAS. Section 49 of the U.S. Code clearly states that the FAA has the power to regulate “navigable airspace.” Here’s the problem: “Navigable airspace” was never really defined. A 1946 court case, United States v. Causby ruled that the National Air Space belongs to the federal government and that states couldn’t regulate it." That has been the law and I don't see the ULC having the horsepower to change it any time soon.
But localities will keep trying.
You can sign up to follow the meetings etc. I have already written an email to protest what they propose and I would encourage everyone on this forum to do the same as most input they get is from lawyers NOT drone operators. If they get their way our industry is dead meat.
