During
these years NASA was not using the familiar logo we know today. Dad received
letters from some of the astronauts on letterhead featuring the old style
logo seen here.
One of those letters
was a hand written note from Donald K. "Deke" Slayton. He was diagnosed
with an irregular heartbeat and taken off flight status. Slayton was assigned
to serve as Coordinator of Astronaut Activities. Later, to the delight
of the entire Astronaut corps, Slayton was reinstated to flight status
and flew on the Apollo/Soyus mission in July 1975.
