Safety:
At the time of me writing this section, it is the 20th anniversary of the September 11 attacks. However, this situation was a transportation anomaly. In reality, airlines are the safest method of transportation. There is no argument against that. We all have greater chances of being struck by lightning than dying in an aircraft.
However, wedging that fact into the heads of many Americans isn't easy. The truth is, most of you reading this don't know how airplanes fly without looking it up and remembering it after reading this sentence. As result, the fear of the plane suddenly falling out of the sky is a consistent fear. More Americans fear being in a plane than in a car, despite the latter being significantly more dangerous. Likewise, despite Amtrak having more serious incidents than American Airlines, more people would sooner be taking the train than the plane. Siderodromophobia is extremely rare compared to aerophobia.
It's worth mentioning that when run properly, trains can never have accidents. The infamous Lathen train collision, unique for involving a Maglev train, only happened due to human error. Meanwhile, no one saw the Concorde's fatal crash with its anomalous circumstances. As a result, the Japanese Shinkansen system has had no passenger/crew fatalities since its inception in the 1960s.
When trains do collide, the people in danger typically are the ones closer to the front, since most train-related issues happen at the driver's end. It's a similar phenomenon with airplanes, and the most danger happens at the front half instead of the back half. However, with some problems, like terrorists shooting land-to-air missiles or what happened on 9/11, there is no escape. I will talk about terrorism later.
