“I was just absolutely adamant about my God-given right to be wishy-washy
about where I was going to land.” Cdr Neil Armstrong
“ In manned vehicles, the same performance goals come easier in a
system not handicapped by idiosyncrasies of the human being…”
NASA Assoc. Admin. Richard Horner

Questions
Is Soar the appropriate tool? What development is needed to model the apollo-like and moderate cases? Can Soar communicate well with other software?
