My penny for a thought;
If one looks back into our possibly fabricated history; ships, horses, camels, elephants and what not were the main source of travel. Then the air balloons and airships came into play; you can see where the downfall begins. Man trying to find methods to imitate the ability to fly (Much like the Icarus story) and finding ways to control flight to one's destination; has always and will forever be a flawed yet useful method to getting around. Things such as the horrific events from 1919 and present; will always have the risk of deaths and misfortune. Unfortunately, we live in a corrupted world where ethics and morals are all interpreted by country and its history. Sadly, it is the risk anyone will take to accommodate easier traveling or convenience for others.
Trains, although loud and what not; are fun and gives off that nice traditional feel. But remember; you can't use trains to travel all over the world. Thus why ships were needed. Unless, we speak of such technology where the fudging train becomes a hover train and what not. If only it was as awesome as the "Polar Express" with such magical Christmasy adventures.
Overall, it is us as humans who create such things whether something damaging to the world or helpful. Where the world is a supply and demand society; tragic events such as plane crashes and explosions will always be an issue.
