If what we learned (from BEA) is adequate to inform us, specially from apogee to SL, we must be impressed how the man-machine interface failed to provide reliable resources to allow the crew to just aviate.
Not as if this hasn't been mentioned already, but let's not forget that, as far as we know, both pilots had very rapidly unwinding altimeters. Those who suspect that PF's displays were farkled have more ammunition for their beliefs thereby, but we really don't know, once again, what PF saw. But really, if neither of them had the altimeter in their scans, that would be shocking. I say this in opposition to the idea that they didn't have enough information to fly the plane.
