Yep, and the fact that the inadequate restraints was the cause of death is an important fact to consider when they build the shuttle's successor.

Consider what would happen if they only put in safety measures to counteract all of the other potential causes of death. You'd still have a bunch of dead astronauts if they used the same restraints, so it's an important lesson to learn.

Not to sound like a 9/11 conspiracy theorist, but didn't they also supposedly find the passport of one of the suspects in the wreckage?

There's a fine line between pretty fucking cool and bullshit, IMHO. I know that saying that makes me sound like a conspiracy theorist, but I evade that label as I have no theory. I just think it's bullshit.

They really need a second experiment, to see if it's evaluated value or initial reaction that stimulates most. IE: Instead of a picture of a real Ferrari, they should have a picture of a model. Good enough that it looks right at first glance, but closer evaluation reveals the differences. Similarly, replace the diamond ring with a glass and gold-plated rip-off.

Then, to really mix things up, replace the 'junk' with valuable stuff which might appear junk at first glance. You need stuff that, when you think about it, is actually worth a lot. Maybe collectibles or something, or a battered-old box labeled "$1M" with the edges of some notes sticking out?
