It looked pretty real to me. I flew Boeing airliners for 25 years, and
the kind of people that might want to make a fake picture like this
one, don't have access to airliner cabins.

Don't need access. Plenty of images and videos of airline cabins on the
internet.

And what about all the
people in the picture? If it were faked, the ones that did it went to
an awful lot of trouble to do it.

No trouble at all. It only takes a little time, money, software, and
computers. Which Hollywood studios have plenty of.

Someone might gain access to an
abbandoned airliner sitting at some airport, but where is one with a
hole in the roof? That plane broke up on the way down, so if it
doesn't fit the collision senario, it had to have been taken after
that. As the passengers have all had time to don their masks, after
they dropped down from the passenger service units. I'd vote the
pictures are the real thing.

OK, you voted. So has everyone else here who responded to your post. You
lose. So do us all a favor. Since we can't convince you, rent the 1st DVD
in the "Lost, Season One" set. Watch the pilot episode, say the first 5
minutes or so. Hit freeze frame. Compare. Then appoligise.

And until proven otherwise, it's
disrespectful to the deceased to say otherwise.

Nobody here is being disrepectful to the poor souls lost on that flight.
However, _you_ are showing some measure of disrespect to their memories for
inadvertently passing on this hoax. Of course, the true losers are the
person or persons that duped you to begin with. Which makes me wonder,
where DID you get this "information", anyway?

A show like survivor
would have mockups of airliner cabins at their disposal,but I never
watch those ridiculous types of shows.

Maybe you should. You'd then see what special effects can do these days.

Someone made a post earlier
that it looked like a scene from that show. That would be about the
only type of organization that would have the resources to fake
something like that.. If it is from that show, someone that watches
it might comment if they really think that's where it came from.

Spend some time at www.snopes.com and look at all of the other hoaxes that
have been and are being foisted on people through the internet. It might
help develop a healthy skepticism in you as well as an appreciation of what
can be done with some time and a computer.

I have a simple rule that I _always_ follow: the chances that I have
"found" something on the internet that NO ONE else on the internet has seen
before is zero. Nada. Zip. Zilch. So I don't post anything unless I can
personally confirm that it is correct. Why? My reputation is at stake. It
takes a lifetime to build it, and only one stupid mistake to ruin it
forever.

People are going to remember "four-oh-four" for a long time to come.
