According to the news I read, Tulane University Hospital, which is owned and operated by Hospital Corporation of America, is being evacuated by helicopters leased by HCA. Charity Hospital, which is across the street, is being evacuated by Guard choppers using the Tulane helipad. These helicopters, as well as ones at the Superdome and the Convention Center, have been fired upon by "civilians."   A number of hotel guests rented buses to get themselves out of the city, but the buses were confiscated by the military to be used for the Superdome evacuation.
