These are some of the most epic experiences in a Learjet 31A
Some of the most beautiful things I’ve seen in life have been high up in an airplane. An extremely hostile yet beautiful and peaceful place. GPS altitude was 52,300 when we were flying at FL510, temp was negative 72 Celsius or minus 98F outside. Atmospheric pressure is only about 15% sea level pressure at that altitude.
