Nobody has yet mentioned that sometimes, if the SID initial clearance ALT is decided by ATC and is not yet known when the cockpit is being set up by PF for departure, some crews will set ALT 00000', as a reminder that the clearance ALT is not yet known. It is not uncommon to conduct a check and briefing of the SID or departure without knowing the initial clearance ALT. Time is limited at turnarounds, and crews will try to get as much done as they can, when they can. I am not saying this is safe, but I know it happens. Some crews will set a strange looking ALT, such as 4,100' or 3,999' to remind themselves.
In some places though, setting a guessed ALT that turns out to be wrong by 1,000' and which does not get corrected could be just as dangerous. It should be possible to display a red "clearance?" flag instead of any figures in the ALT window for those places where initial climb ALT is given by ATC as part of the clearance.

Very odd though, if none of the 4 pilots noticed the lack of pitch-up following the 'Rotate' call. They must have noticed, so was there a pitch control problem?
