“I ventured up onto the domes of the world's largest telescopes a few times. The view was impressive! The curvature of the domes means that you can only walk around on about twenty feet of the domes before developing a fear of sliding off them on the rapidly sloping surface. What amazes me today was that I was not required to wear a safety harness during the fun activity while breathing very high altitude air that was 40% deficient of oxygen that was known to make people faint. A strenuous climb up ladders was required to get to the top of the domes and a fall from that height would likely be fatal.” — Steven Magee
