You are definitely not a USA resident! Thanks to those auctions we have an oligopoly of carriers who charge per GB like it is a gallon on Nobel Prize winners' sperm, while delivering service that compares unfavourably with a 56K modem on a bad line.

In most of the US opening a heliport is incredibly simple; take your parking lot or other land and paint some markings on the ground. Shoot off a letter to the FAA. Done.

That said, rotor-craft are not even required to land at a heliport; they can land anywhere that is safe unless doing so is trespassing or forbidden by a law.

A license auction would only restrict access and stifle competition.

You'll find somepeople in Govt will get bought and then the goal posts will be moved. Its std democratic practice.

Does your opinion change if they weren't really audible except for at the ports? There's actually been a lot of research into making them quieter. It could end up quieter than street traffic, except for at the ports where they're taking off and landing.

Hard disagree. Helicopters are much less safe and not have redundant batteries or propellers. Joby recently provided acoustic results with NASA that show magnitudes less dB, you can look it up and hear for yourself. Having witnessed hundreds of Joby flights I can say from experience that it doesn’t seem any louder than a distant vacuum cleaner, I could hold conversations nearby without strain. Living by a highway with motorcycles was worse. I learned a lot about aviation lately and having also been in a helicopter and I sometimes think back that it was a stupid risk to take without having my affairs in order, never mind the aviation fuel, what disgusting fumes!
