I agree with Tango regarding agressive moderating lately.

Regarding the curtain, this and all the other "security" improvements like not walking between cabins are a bit much. We have to take the risk of terrorism in proportion to probability- I mean how many people die every year in car accidents (44,000). Yet the government and airlines spend so many billions on security. Dave N. hit it right on when he said if it really were safety then other airlines would do it. The perception of the threat is much greater than the actual risk.

Death tends to come in little tragedies, not big ones like hijacking.
