I don't know about space shuttle software, but there are lots of computers that run nothing but ForTran-66 programs or older being put through the latest ForTran compilers. Of course they use line editors on their shiney new VT100s because they don't know about about screen editors. There are only a few groups changing (oh-so-slowly) over to the radical new languages that can out in the early 70s (Pascal and C). Although, the shuttle software was written by IBM people under contract, so they probably used a mish-mash of PL-1 and ForTran. There was also work down by Rockwell that I'll guess is a mish-mash of Jovial and ForTran.
