Surprising Facts

A collection of facts that I found surprising:

1. Availability of animals for domestication was the reason for deadly animal-human disease transmission and the death of 90% of American indigenous population. And the lack of domestic animals in the Americas was the reason why there was no American plague spreading in Europe.
2. The Wright brothers did not invent flying in the general sense but they invented controlled flying by overcoming adverse yaw during rolling maneuvers.
3. The root cause of the oxygen tank explosion in the Apollo 13 mission was using 60V during ground operations on 28V rated oxygen tank to boil off oxygen in the tank which led to welding of the thermostat and the eventual burning of wire Teflon coating.
4. The Linux Kernel has thousands of goto statements.
