Im joining the british army and I am wondering how much leave will I get during phase 1 trainjng?

Because they don't. People who fly high performance AC fly them so they do not pass out when experiencing high g-force and extreme altitudes. Many military aircraft are fully pressurized and only use o2 masks if there is an issue with pressurization or smoke in the cockpit.

I worked on aircraft environmental systems on military aircraft for about 20 years. The rest of these military trolls do not know what they are talking about.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
