Well, I'm not commenting for LockMart (great name though :-)  I do Ada for
another LM division, but my system is quite land-based. Though it might be 
preaching to the choir here, I really have to point out that the Ariane 
failure was in no way related to Ada (or any language) but rather a PROCESS 
failure. Nobody documented the "shortcut" taken (no exception handler), so 
nobody knew it wouldn't work in other flight regimes, so nobody tested it, 
so the rocket blew up.  Kind of a graphic demonstration of the "hidden" 
costs of software engineering shortcuts, eh?

Just my $0.0122 ($@&!^@ withholding taxes)
