I came across this paper which, on page 9, says the following:
The guidance or “shooting” algorithm is based on the Linear Peturbation Theory (Battin) developed for the America’s Program for Orbiting Lunar and Landing Operations (APOLLO) program during the 1960s.
Now, I can't tell whether the APOLLO program referenced in this sentence is the Apollo program (the one that landed people on the moon in 1969-1972). Is this sentence referring to a different APOLLO program than the one I thought of when I saw the word Apollo? If not, was the name of the Apollo program really an acronym as indicated in the quoted sentence?
