I have to admit that I share Bill's reservations about this
claim.  In my career I've dealt with some systems coded in 100%
Ada that were so awful the only recourse was to recode them, in
effect blowing the schedule and budget even worse.  However,
that was the only way to remedy the problem.  The cause of
this was certainly not Ada, but were all programmatic issues
of unrealistic schedule, micromanagement, and requirements that
changed more frequently than ABC's summer rerun schedule :-)

And unfortunately Ada got caught up in "guilt by association".
Very few observed that when "another **** Ada exception crashed
the system", this was actually a good thing, because range
violations and null pointer checks could've easily gone
unnoticed if coded in other programming languages.  However,
that was faint praise for Ada in the context of that project.
