Raising Awareness, Lowering The Odds
I gather this is in the USA only and includes ultra light and light aircraft, helicopters, balloons, military etc - all pretty high risk - on top of commercial airplanes.
So I would think that this brings the likelihood of being killed in a commercial flight down dramatically.
Yet, passenger safety on a commercial flight is paramount and tried and true systems are in place for all passengers to openly engage in and follow in case of an emergency. Knowing the plane could fall out of the sky at any moment causing instant death does not deter millions from flying.
Parallels could be drawn with lethal Box Jellyfish where the odds of being killed are not great - we'll have to get Thailand's NSC onto the stats!! - but it does occur and the results are devastating so similarly there should be systems and processes in place to minimize the risk...as there is with fire safety plans in office buildings and as there is with tsunami warning systems along the coast.
We know that there are potentially lethal jellyfish in Thailand's waters, we know that people receive near-fatal and fatal stings and we know that if it keeps going tourism will potentially be severely hit everytime a death occurs until visitors vote with their VISA cards and go for a swim somewhere safer like Fiji, Bali, the Caribbean, etc.
So while a risk exists it is important for all concerned that the truth be made public and that the public be given the best opportunity to survive in case of the inevitable emergency - and with Box Jellyfish it is easy: vinegar available on the beaches (in a pole or station, or the front bar of a resort/hotel/restaurant, or carried by the individual), locals including resort staff be made familiar with the first aid treatment and individuals take responsibility and wear lycra stinger suits - particularly innocent children who through the habits of both the Box Jellyfish and the child have much, much higher odds of being killed.
Here are photos of a vinegar station at Broome in West Australia's famous and very popular Cable Beach which doesn't stop loads of people enjoying the water their every day. At least they know what to do just in case.
