If we had to fight for or defend Singapore, what would you be fighting for? What would you be protecting? Pin it down.

Changi Airport - the way out (Me)
"Very important area to defend - the airport. So that you can get out if need be."


Changi Airport (jim)
"So my family can go somewhere else..."

Looks like someone else had the same idea...


Addendum:


Chicago O'Hare Airport (AcidFlask)
"I'd fight for my right to walk through the immigration counter here."

This is an even better idea!
