The fact that the passengers disappeared seamlessly would indicate that they were willing participants by and large. It is plausible to believe that some passengers were just regular people, and randomly chosen for death & disappearance on 9/11.his constitutes our 2nd conundrum regarding the passengers and the 4 flights on 9/11. 2 groups of people, one from flight 11 at Boston and one from flight 77 at Dulles would both seamlessly disappear under similar circumstances. And both groups of people would never board either of the flights, 11 or 77.
Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Normally, the atria are separated by a dividing wall, the interatrial septum. sinus venosus ASD is a type of atrial septum defect in which the defect in the septum involves the venous inflow of either the superior vena cava or the inferior vena cava. A sinus venosus ASD that involves the superior vena cava makes up 2 to 3% of all interatrial communication.
Atrial septal defect (ASD) is one of the more commonly recognized congenital cardiac anomalies presenting in adulthood. Atrial septal defect is characterized by a defect in the interatrial septum allowing pulmonary venous return from the left atrium to pass directly to the right atrium.tiology. Atrial septal defect (ASD) is a congenital cardiac disorder caused by the spontaneous malformation of the interatrial septum. Ostium secundum ASD: This type of ASD results from incomplete adhesion between the flap valve associated with the foramen ovale and the septum secundum after birth.
