I assume you do know that it was not the computer hardware but the phyiscal paremeters (acceleration) of the rocket itself? >Last not least: Runtime check where disabled for that incident. So if >anything: this incident speak in favor of runtime checks. They were disabled in the Ariane 4 software after it was *proven* that the exceptions could simply not occur on an Ariane 4. If the runtime checks were not disabled the software would not fit so the rocket would not fly. I am not sure that's the preferrable alternative. If this accident speaks for anything IMHO it speaks for sensible management. Which is apparently a problem on both sides of the ocean :( Wouter van Ooijen -- ------------------------------------ http://www.voti.nl Webshop for PICs and other electronics http://www.voti.nl/hvu Teacher electronics and informatics
