Although I have learned the logic, and despite spending my professional life around aviation, I still find it incredible that a chunk of metal filled up with people, baggage and cargo can take to the sky. Not only does it do this, but it happens almost every second of the day and night somewhere in the world and it is promoted as being safer than getting in your car. Absolutely incredible--and a testament to the designers and builders who create these amazing, and mainly reliable transporters of people and goods across the world.
Long may it continue; however, the modern world has come up with at least two major challenges to this status quo, and they are terrorism and the acute competition between airlines in a recessionary market.
