We flew over Port-au-Prince Monday to survey the damage with members of the 82nd Airborne Division. I shot this video from a Blackhawk helicopter.

You can see the crowded conditions that existed before the earthquake hit Jan. 12 and the virtually empty streets.

Many people have told us they are afraid to go back into buildings damaged by the 7.0-magnitude earthquake. Thousands have gathered in open-air spaces like parks and golf courses to wait for help.
