The present day facility incorporates the site of the first official Grand Canyon airport, a landing field authorized by the U.S. Forest Service for commercial flights in 1925. The new airport first opened for business in October 1965. The airport terminal was completed and formally dedicated on October 20, 1967.
Researchers arenât sure what causes placenta previa, but it is slightly more common in older mothers, women with a history of prior cesarean section or abortion and women with a history of smoking or cocaine use during pregnancy.
If the placenta attaches to the lower part of the uterus, it can cover part or all of the cervix (the entrance to the womb). When the placenta covers part or all of the cervix during the last months of pregnancy, this is a condition known as placenta previa, or low-lying placenta. This condition can cause severe bleeding before or during labor. There are four types of placenta previa, ranging from minor to major (in which the placenta is covering the entire opening of the cervix). Depending on the type, a woman with placenta previa may need to have a Cesarean (C-section) delivery.
