Yes, the BBC never showed it. They started showing season 9 in October 2001, and they were obviously never going to show it that soon after the fact, and by the time they lost the rights to the show in 2004 it was clearly still considered too soon.

However they did show The Cartridge Family as part of that season 9 run, and I'm pretty sure uncut, which Sky had always refused to show until then (so it ended up getting released on VHS instead). Sky were always quite edit heavy with The Simpsons, though they did restore a lot of cut material in the early 00s. Channel 4 however seem to be even more snip happy, even cutting out stuff that Sky left in when they were most scissor happy in the 90s.

On a related note, I went to the 9/11 museum in New York back in November, one of the most harrowing things I've ever done- some stuff there is very disturbing- but I would say anyone going to New York has to go, so you can properly understand just what happened that day. Makes me despise the "truth" movement more than I already did.
