U.S. official: We're improving aid to Haiti

Washington (CNN) - Stung by criticism that aid hasn't been getting into earthquake-ravaged Haiti quickly enough, U.S. officials say they are taking steps to rectify the problem and the perception.

A senior administration official involved in the aid operation acknowledged Wednesday that not all aid, particularly medical supplies, was getting through fast enough and attributed it to two factors.

Dozens of planes were flying into the Port-Au-Prince airport in Haiti, carrying a variety of food, water, medicine and search-and-rescue gear.

The official, who spoke on condition of anonymity, said military personnel on the ground were sometimes confused about what each plane was carrying.

The military will now station aid officials in the airport control tower to assess the contents of each flight and to ease the flow of aid, the source said.

Also, a Web-based system has been created so that aid groups, donor countries and others can track when each flight is scheduled to land and the supplies it has aboard.

The official also said the operating procedure of the U.N. Stabilization Mission in Haiti (MINUSTAH) says it can work without security only during daylight. The arrival of U.S. troops means they can take over a large share of security and speed the processing of aid.
