US Air Force log documenting activity at the airport obtained by the Associated Press largely disprove the claim that the US held up aid in favor of military flights . The US military initially did give priority to military units needed to secure the airport , distribute aid , and provide security , but after that , incoming relief flights was cleared or rejected on a first @-@ come , first @-@ served basis .

Those flights that was rejected was diverted to the Dominican Republic , where their cargoes was unloaded and taken to Haiti by land .
