By the way, if anyone wants to read the two papers for themselves:
Ariane V final report:
http://www.esrin.esa.it/htdocs/tidc/Press/Press96/ariane5rep.html
Eiffel paper on Ariane V:
http://www.eiffel.com/doc/manuals/technology/contract/ariane/index.html
which contains the now-infamous quote:
"Does this mean that the crash would automatically have been
avoided had the mission used a language and method supporting
built-in
assertions and Design by Contract? Although it is always risky to
draw
such after-the-fact conclusions, the answer is probably yes:"
Note the term "language and method." As explained later in the paper,
only Eiffel meets the required criteria. Both are required, per Meyer.
