Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.

The Domestic Violence Legal Assistance Program fills the gap of legal resources for domestic violence survivors who can't afford an attorney. Domestic violence survivors in Jackson, Vicksburg, Hattiesburg, Oxford and Pascagoula can all get help. Julia Crockett, deputy director of Central Southwest Mississippi Legal Services Corp., said the program expects to help nearly 1,000 domestic violence victims. Crockett said legal help gives domestic abuse survivors a way to rebuild their lives. "They have been made to feel by the abuser that no one is going to help them do anything, so when they come to us they are desperate," she said. "Those who need legal help and don't get it feel totally lost. Because then they feel like they are forced to stay in that situation." Crockett said the program, funded by a $300,000 grant from the U.S. Justice Department, has no economic restrictions on who can get help. Legal services typically helps the poor. Gladys Bunzy, who said she was in an abusive relationship with a boyfriend for eight years, said such a program is long overdue and could be a lifeline for those escaping violent relationships. "When I finally made up my mind to leave, I had a restraining order put against him and that was $50 but that was $50 well spent to me," said Bunzy, 40. "For people who can't afford it, this will be a godsend ... If a woman knows she is going to get some help that will be a burden off her mind, if the law will help her keep that person away from her." Gwen Bouie-Haynes, project director of the Domestic Violence Services Center for Catholic Charities Inc., said often domestic violence survivors do not have the money to seek legal representation. "Legal assistance is a major issue for women fleeing a domestic violence situation," she said. "Often times women are in need of immediate legal assistance services for the protection of the mother and the child. To get a protective order you need to be represented by an attorney." Crockett said the pilot program was launched in 1998 at the Haven House Family Shelter Inc., a domestic violence shelter for women and children in Vicksburg. The program has helped victims in 90 court cases, and 150 legal counseling sessions have been held there.

Right after the Pentagon was hit, NEADS learned of another possible hijacked aircraft. It was an aircraft that in fact had not been hijacked at all. After the second World Trade Center crash, Boston Center managers recognized that both aircraft were transcontinental 767 jetliners that had departed Logan Airport. Remembering the "we have some planes" remark, Boston Center guessed that Delta 1989 might also be hijacked. Boston Center called NEADS at 9:41 and identified Delta 1989, a 767 jet that had left Logan Airport for Las Vegas, as a possible hijack. NEADS warned the FAA's Cleveland Center to watch Delta 1989. The Command Center and FAA headquarters watched it too. During the course of the morning, there were multiple erroneous reports of hijacked aircraft. The report of American 11 heading south was the first; Delta 1989 was the second. NEADS never lost track of Delta 1989, and even ordered fighter aircraft from Ohio and Michigan to intercept it. The flight never turned off its transponder. NEADS soon learned that the aircraft was not hijacked, and tracked Delta 1989 as it reversed course over Toledo, headed east, and landed in Cleveland. But another aircraft was heading toward Washington, an aircraft about which NORAD had heard nothing: United 93. United Airlines Flight 93 FAA Awareness. At 9:27, after having been in the air for 45 minutes, United 93 acknowledged a transmission from the Cleveland Center controller. This was the last normal contact the FAA had with the flight. Less than a minute later, the Cleveland controller and the pilots of aircraft in the vicinity heard "a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin." The controller responded, seconds later: "Somebody call Cleveland?"This was followed by a second radio transmission, with sounds of screaming.
Two radio transmissions that included (possible) screaming came from which aircraft?
