Poison gas, firing squads: US approves more execution methods

[forgotmylogin]

56. I've also read that of controlled hypoxia. (Same thing?)

No gas necessary, just a sealed chamber where oxygen can be removed. (Perhaps this is the same thing? Flooding a chamber with nitrogen to push out the oxygen?)

They subject fighter pilots to it so they are used to low-oxygen atmospheres and emergencies and they can learn to recognize the effects and try to work through a crisis.

A journalist on a (BBC?) video experienced it and said it was oddly euphoric and not painful before they stopped the process so he wouldn't die. They said a subject during execution would feel tired and drift calmly to unconsciousness well before death.

(I'm not for death penalty in general, but this sounded like the closest method to "humane".)
