Do you have any idea how mad you sound?’‘Indeed I do. I have in moments of doubt considered the question of my sanity.’ (...)‘And?’‘Then I consider what a piece of work is man. How defective in reason, how mean his facilities, how ugly in form and movement, in action how like a devil, in apprehension how like a cow. The beauty of the world? The paragon of animals? To me the quintessence of dust.

My memories of my time in high altitude astronomy indicate that there were no oxygen concentration monitors or alarms in the areas that liquid nitrogen was in use at the high altitude astronomical facilities where I had worked.

In high altitude astronomical facilities we routinely discharged large amounts of nitrogen gas into closed spaces. We were never informed by the astronomy management team about the abnormally low oxygen environments that the use of liquid nitrogen creates, how long term exposure to it manifests itself in human health and the resulting abnormal mental behaviors.

Based on the medical evidence that clearly states that being above 10,000 feet is hazardous to the health of sea level adapted humans, it is clear that all of the manned facilities on top of the 13,796 feet Mauna Kea summit in Hawaii should be removed and the summit restored back to its native environment.

This fits in with what I saw in staff in astronomical facilities and was reporting to the management team: 10-14% Oxygen: Emotional upset, abnormal fatigue, disturbed respiration.
