The NTSB Charter has been changed since 1974. Does the agency need a new one?

...In 1974, Congress reestablished the NTSB (click here) as a completely separate entity, outside the DOT, reasoning that "...No federal agency can properly perform such (investigatory) functions unless it is totally separate and independent from any other ... agency of the United States."...

"The Sterile Cockpit," (click here - ASRS is a branch of NASA) is often, all too often, cited in NTSB formulas for aircraft failures. In other words, the pilots were not following the rules. This rule is in the current charter and the NTSB is required to cite it if there was any indication on the Voice Recorder.

The Sterile Cockpit is used by Commercial Airline Manufacturers to explain away their liability is primarily assigned to pilots breaking the rules. It places liability on the Carriers and Pilots rather than anywhere else.

The Sterile Cockpit is a myth. The Cockpit / Flight Deck crew talk before leaving the ground. It is a matter of bonding between people who have never worked together and provides an opportunity for pilot and co-pilot to become comfortable with each other. IT is a myth built into the NTSB Charter that is used as a legal liability tool. Where are the Unions on this and why hasn't it been amended in the current Charter to reflect REAL LIFE scenarios and practicality? I mean I know Congress is worthless these days and obstruction is everywhere, but, this is life and death. How can the NTSB function completely in a positive outcome if they have to cite hideous and outdated regulations?

It's no secret. (click here) When a flight crew's attention is diverted from the task of flying, the chance of error increases. Over the years there have been dozens of air carrier accidents that occurred when the crew diverted attention from the task at hand and became occupied with items totally unrelated to flying. Consequently, important things were missed. Things like setting the flaps prior to takeoff, or extending the landing gear before landing. Things like monitoring altitude on an instrument approach, or using engine anti-ice for takeoff during a blinding snow storm....

"Sole Survivor" states all occurred at the age of 17 or younger. There is one characteristic young people share at that age. It is called the Epiphyseal Plate otherwise known as The Growth Plates. Growth Plates end their purpose at the age of 20.

Noted in this picture the Epiphyseal Plate/Growth Plate is boardered in majority by what is called "Spongy Bone." Cortical Bone is the hard exterior bone. Spongy Bone is known to physicians and surgeons as Cancellous Bone.It is illustrated here in the smaller picture.


This type of bone is very vascular. It has a lot of squishy properties. The squishy properties provides for compressibility. Compressibility allows shocks to the tissue to be absorbed without causing injury. All the Sole Survivors, as children, grew up just fine. 

I sincerely believe one of the reasons George survived was because he was actively kicking the bulkhead wall in front of him and absorbing the shock of the crash at the same time. He was seventeen. He stated his kicking drove him outside the plane while it burst into flames. Perhaps bringing knees to the chest to put the feet on the seat in front of you is a better strategy than bending over with a person's face in their lap. In that posture one can still reach the oxygen masks when they fall. It is not a position every passenger will be able to achieve, however.

It is not all positioning and bone, it is also physics. Planes are not crash proof. They never will be. 

I believe George's mental state after the crash was due to the fact he fought for his life at the time when he survived. He also had his mother. The trauma bond with the accident was significant and he ultimately returned to live in the city where he lost his father. He also suffered from elated invulnerability as if Superman. He tested his ability to continue to survive by racing cars at high speeds, etc. Trauma bonds will do strange things. Most of the survivors were bonded to the crash and it played a part in their daily lives thereafter.

It is an excellent documentary. It makes many, many interesting and insightful points.
