It wouldn't be the worst thing in the world if they banned sightseeing helicopter flights entirely. They were already banned from overflying Manhattan decades ago after a particularly fatal crash, and serious crashes continue at an average rate of one per year, including one in 2009 that killed nine.

The most unappreciated aspect of the helicopters' impact, though, is the noise. They ruin the possibility for enjoyment of the waterfront for a several block radius around every pier that they use. When you run or bike past the piers along the waterfront you have to stop your conversation, they're that loud. And the combustion vapors they're giving off aren't pleasant either.

It really would contribute to the greater safety and enjoyment of all if they fully got rid of these flights. At least get their launch sites away from Manhattan, where they spoil the peaceful enjoyment of huge swaths of public waterfront.
