If people working in security forget about it then they should be fired for being incompetent, but people who are not involved with such things, and have no reason to remember 9/11 because they weren't actually hurt by it have understandable reasons to not care about 9/11, the world doesn't revolve around US of A and its problems.
Look on the bright side, being killed by a parasitic cannibal suit is a way more metal way to die than just by cancer, sucks if someone without cancer dies by it anyways though

The game shows the symbiote on the plane:
At 54:03, dunno about the comics.

Yeah that was part of the reason Ultimate comics started to suck (Even if there wasn't much good **** outside of Spidey), it became about as convoluted as 616, with not even 1/3 of the time of publication, think even without Ultimatum it would be doomed to die off eventually, all Ultimatum did was speedrun its death, although it surprisingly lasted for a while even after that.
Ultimate comics ending at Ultimatum would mean no Maker or Miles, so it'd be significant to have ended that early.
