| During the course of my investigation of United Flight 823, I have made several attempts to obtain testimony given during the Public Hearing that took place in Knoxville, Tennessee from January 12 until January 16, 1965. The different inquiries that I have made have received the same response: "The requested documents can not be found". | During the course of my investigation of United Flight 823, I have made several attempts to obtain testimony given during the Public Hearing that took place in Knoxville, Tennessee from January 12 until January 16, 1965.

| The document is very helpful in that it refers to testimony that was given during the hearings and brings to light testimony that differs from the conclusions found in the final Civil Aeronautics Board report-the most important of which was contrary testimony provided by the Bureau of Safety which United Airlines claims to be a "major point of dispute". | The document is very helpful in that it refers to testimony that was given during the hearings and brings to light testimony that differs from the conclusions found in the final Civil Aeronautics Board report-the most important of which was contrary testimony provided by the Bureau of Safety which United Airlines claims to be a "major point of dispute". | ||

| Second, the information regarding Sonotone batteries that I have found in United Airlines and Capital Airlines flight manuals from the early 1960s do not mention dangers or risks involved with the use of Sonotone batteries in Vickers Viscount aircraft. In fact, it is my opinion that the Airworthiness Directives and Advisory Circulars directly contradict the information provided in the aforementioned flight manuals and show how a false sense of security was made possible with regard to Sonotone batteries. | Second, the information regarding Sonotone batteries that I have found in United Airlines and Capital Airlines flight manuals from the early 1960s do not mention dangers or risks involved with the use of Sonotone batteries in Vickers Viscount aircraft.

| + | **UPDATE:** Correction. [[FAA Order WP 6000.6 Ni-Cad Batteries 8/8/66|An ORDER from the FAA, dated, 8/8/66]] was issued with regard to nickel cadmium batteries. This bulletin included a discussion of tests performed on ni-cad batteries and methods used to charge them. Corrections via Airworthiness Directive 71-21-5 concerned the different types of battery cases that comprised Sonotone Batteries and their tendency to overheat, while the later Advisory Circulars were refinements of the FAA Order of 1966. | ||
