There are numerous types of oxygen available for purchase. These are industrial oxygen – generally for welding and not suitable for human consumption, aviation oxygen – regulated by the FAA rules, medical oxygen - regulated by the FDA and DOT. It was unclear what type of oxygen was inside the oxygen cylinders that employees were using at the summit of Mauna Kea and most employees assumed it was medical oxygen for treating their medical conditions.

There were numerous times that I was trying and failing to shut down the world’s largest telescopes at the end of the night shift. I would eventually have to leave it to the day shift, as my confusion from prolonged exposure to abnormal environmental conditions was too severe to complete the task.

While I was aware of three workers that had disclosed their gender issues during their time in high altitude astronomy, I was not aware of how many more were staying silent about it.

Improved health did not come from a corporate health care system, it came from my girlfriend putting me on a gluten free diet.

Nepotism made it extremely difficult to function as a manager in certain high altitude observatories.

Mauna Kea will not be a clone of Standing Rock.

With the benefit of hindsight, it was a serious mistake to think that the modern corporate healthcare system could accurately diagnose and treat me.

I guess when it come to corporate government science interests, the inconvenience of worker sickness will be covered up.

Regarding the Thirty Meter Telescope (TMT) atop Mauna Kea, I am interested to know how much the international astronomy community has spent on advertising the biologically toxic project to the masses and how much has been spent on researching High Altitude Observatory Diseases (HAOD)?
