"The hole is about 6 feet, oxygen masks are down," passenger Brenda Reese told KCRA 3. Reese said she was asleep when the rapid descent took place but heard a jarring noise.
I caught some pics on another site and from the inside it appears that the hole/tear is at least 4 ft long. The previous fuselage problems have been holes about 8" x 12". We will have to wait on this one to see if there was a large failure from the start or airflow over the fuselage increased the size of the hole.
