Two out of three

Houston, The Eagle has landed! Those words were spoken by Neil Armstrong as he and Buzz Aldrin landed on the moon in the Lunar Module. While Neil and Buzz landed and walked on the moon, somebody had to orbit the moon and monitor operations. That somebody was Michael Collins. Michael Collins died today. Neil Armstrong died in 2012. Now Buzz Aldrin is the only remaining member of the Apollo 11 crew. Godspeed, Michael Collins!
