Aerospace Daily said that the current explanation was an erroneous command
from the flight control computers to the nozzles, driving them all hard over.
Such a command could be due to software, or to interface electronics failure,
or possibly noise on the wire connecting the two. I wouldn't be ready to
blame the software just yet.
Of course, assuming that the root cause is traced to the software, what of
it? Using Ada certainly doesn't ensure proper operation of a software system!
