ELI5: Why can't compressed oxygen be transported to india on planes, only on roads and trains?
gpt
Containers filled with oxygen are generally not transported on board aircrafts as they are considered combustible and may pose a risk to the planes. Oxygen behaves differently to nitrogen and other inert gases. It is very reactive. Even a small increase in the oxygen level in the air to 24% can create a dangerous situation. It becomes easier to start a fire, which will then burn hotter and more fiercely than in normal air.
