I don't know if I'd use the term "quality" to describe the code what
came out the other end, but it did work pretty solidly once delivered to
customers.  I used to wonder why it didn't collapse.  I think the main
thing protecting it was that it didn't have to deal with unrestricted
user input like a desktop application, or do much complex processing
like a compiler does.  Each unit was configured and tested before
delivery and I guess not reconfigured once in the field.  So it was in
some ways like an appliance: just a few combinations of input were
possible once it was in the customer's hands.

Wishful thinking.  It was designed by electrical engineers who were
smarter than hell but didn't know anything about software.  So they were
able to write crazy and intricate code and actually get it to work, but
it was near-unmaintainable (premature optimization was a recurring
theme).  It had tons of written specs per ISO 9002 but the specs didn't
have much to do with the internals of the code.

Meanwhile I hear that SpaceX is using C++ to program what will
eventually be manned spacecraft.  Shudder.
