True, but there is reason to believe that it is simpler to obtain a
reliable runtime system for a programming language then for a flight
control system. Not only is the flight control system depending on the
runtime system (adding an additional layer of complexity), but also for
several reasons it is easier to test and mature the runtime system. The
runtime system does not need a complicated testing environment and gets
tested every day by each of its users. By the time it qualifies for
space, it will have had its child diseases.

Unfortunately, one major software firm is well known for using its
customers as unpaid beta-testers....

Groeten, Karel
