That building is probably the health club near the Sky Chief. It's hard to tell from that picture. The hospital is not near the crash site. The closest landmarks would be the Country Club, Sonora Nissan, Napa, and the Wal-Mart on Pacific.
Regarding the picture in question from a previous post. If you look at the tag line in the photograph, you will see that it was supplied by KMYA news channel 11. The station is located on Pacific Avenue, but in the North valley. This is apx. 2 miles from Wal-Mart on the mesa, where the plane went down behind it. The building that you see in the picture is the Shiloh Inn hotel located on 16th Street (or Highway 95) and the I-8 entrance ramp. KYMA has a roof camera that they use generally when they are broadcasting weather. Hope that this has helped you with your Yuma geography.
