I dunno. Call me kooky, call me wacky, but I can't shake the suspicion that a lot of the anti-AI/AF/Ziegler posts on this thread are from various pseudonyms of M. Jacquet himself.
I remember reading many moons ago that the GPWS was not mandated on Air Inter's A320s because at the time GPWS was still having the bugs worked out - giving many false positives, and Air Inter had been in direct competition with the TGV high-speed rail network since 1981 and couldn't afford to have any delays.
I'm not denying the behaviour of the state-owned Air Inter was more than a little ill-advised, but you can't blame the aircraft for that.
