One particular source that I found most useful was the evidences in the book New Zealand Tragedies Aviation: Accidents and Disasters, by John King, which I found was most useful in answering focusing question 3, which is on the outcomes and significance the disaster of Erebus had on the people involved in the recovery operations. I also think it was quite useful in finding relevant evidence that answers both focusing question 1 and focusing question 2. As the majority of my other sources that answers my focusing question 1, in what seems to a repetitive form of what I had already obtained from the NZ History website, it is mainly why I found this book more useful as it expands on the information in a more detailed manner, which enabled me to explore on a specific area more deeply. Thus, the quality of the evidence was good that made this source being the most useful. Although, due to my timeframe being shortenend as highlighting took too long, I was not able to go further annotate more pages that seemed to be useful towards my focusing questions, but have chosen what I believed to be most relevant and useful for my focusing questions. This book is a secondary source containing primary evidences, such as photos of the crash site and the transcript and it can be seen from the information available in this book that the author has used a wide range of sources to gather his information (as seen in his bibliography), containing factual information on the Erebus disaster. Though, it should also be taken into account what type of evidences the author’s using, as John King, author of this book, used the Chippindale transcript, in which reliability issues arise in such a manner that it limits the reliability and accuracy of the work and evidences that King has provided, since the transcript has been proved to lack in accuracy – differing in 55 ways when compared with the original Washington transcript. Therefore when reading the transcript in this book, extra caution would need to be taken but although the transcript differs from the original one, its usefulness should not be dismissed; as a usefulness of a source does not only depend on its reliability, although it does play a large factor. Since, a source may be useful, despite being slightly biased or altered to suit one’s needs, but will lack in the aspect of reliability. There was one source in which I found relatively useful but was lacking in detail was the Te Ara – The Encyclopedia of New Zealand website. In this website I had only found one page relating to the Erebus disaster, which had some good evidences that helped answer all my focusing questions. It summarized information on what happened in a small section, which I found not that useful as it wasn’t detailed enough to come to any conclusions. I found that the evidences only useful as a general overview and a start point into investigating the topic but there was the need to refer to other sources for more in depth information. The TVNZ’S Lookout: The Mt Erebus Disaster documentary, I found was more useful for focusing question 2 and 3, as it went contained primary evidences of the inquiry footage, which allowed me to look into the controversy of the causes and the outcomes of the disaster in depth.
