So i was reading in the astronaut factbook today.... and I came across this entry under "Deceased U.S. Astronauts" (among all the astroanuts who died in plane crashes, etc):
HENIZE, Karl G., Civilian
Born October 17, 1926, in Cincinnati, Ohio.
Bachelor of Arts in mathematics from the University of Virginia; Master of Arts in astronomy from the University of Virginia; Doctor of Philosophy in astronomy from the University of Michigan.
Flew on STS 51-F.
Cumulative hours of space flight are more than 190.
Died October 5, 1993, of respiratory and heart failure during a climb of Mount Everest.
So tell me... who else but a former astronaut would be climbing Mount Everest 12 days before their 67th birthday?
*BTW, Harrison Schmitt was a Doctor of Philosophy in geology from Harvard University.*
