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.
The main symptom of placenta previa -- and the greatest risk to you and your baby -- is vaginal bleeding. If you have bled too much, you may have other symptoms, such as anemia, pale skin, rapid and weak pulse, shortness of breath, or low blood pressure. The bleeding that signals placenta previa may occur at the end of the second trimester or beginning of the third trimester. It may be heavy or light. Bleeding is usually painless, and it may happen without labor or during labor.
