These were designed for egress before the smoke becomes a problem. If your gonna demonstrate this, then you need to demonstrate exit signs as well.....

It is very unfortunate that this type of technology was not available to the workers trapped inside the twin towers during 9/11.
I hope they use these in the new Freedom Tower at ground zero.
