Everyone has to decide what they are comfortable with, but for us, the Stats speak for themselves:
Hawaii experiences a relatively high number of helicopter crashes, particularly in the air tour industry. Since 1984, there have been 54 commercial helicopter crashes in the islands, averaging about one to two per year. Fifteen of these crashes were fatal, resulting in 57 deaths
Certainly risk level is an individual choice, but I also think to make that choice, you need to have an accurate assessment of the real risk.
Looking at the limited info available online, it looks like there are somewhere around 100,000 tour flights every year in Hawaii. So, that "relatively high" 1-2 crashes per year means there is, around a 0.002% chance your flight will end in a crash. That's a safe flight completion rate of 99.998%.
The 99,998 safe flights don't make news. The two accidents are blasted around the world online and in the broadcast media. For the average person who doesn't understand how statistically safe all of aviation is, those headlines can be really scary.
Last week, a mother and her four young children died in a fiery car crash on Interstate 95 south of Savannah while on the way to Orlando. I doubt very many people will resolve never to drive on an interstate highway because of that crash. But sadly, since aviation is much more foreign to most people, I'm sure the video and headlines of the tragic helicopter crash in New York City will cause some people to assume that flying on helicopters is much more risky than it really is.
As an aside, for the last 20 years, I've worked as an aviation journalist covering what probably is statistically the riskiest part of aviation - the airshow and air racing community. Over the last two decades, I've unfortunately lost quite a few friends and acquaintances in airshow/air race accidents. But even in our little niche of aviation, due to effective FAA regulations and professionalism, almost all practice flights and performances result in safe landings. Just doing some back-of-the envelope math, I'm pretty sure airshow performances and practices have a safe completion rate of well over 99% as well.
Aviation can kill you. Driving on the interstate can kill you. You can die snorkeling or hiking. Only engage in the activities you are comfortable with, but don't let sensationalist screaming headlines dissuade you from activities that are really very safe.
