Below is a link to an article from ProQuest Historical New York Times. It is an interview with Harold Bride, a radio transmitter, who was working aboard the Titanic when it sank. Bride survived and was interviewed days after the event for this article. (You do not need to read the entire article.)
Bride, Harold. "Surviving Wireless Operator of the Titanic. Thrilling Story by Titanic's Surviving Wireless Man. Bride Tells How He and Phillips worked and How He Finished a Stoker Who Tried to Steal Phillips's Life Belt". New York Times (1857-1922), Apr 19, 1912, pp. 1. ProQuest, Accessed 7 May 2021.
First-hand accounts of events are considered primary sources of information. A secondary source would be someone else describing what Bride experienced. Primary sources are excellent resources for research papers. You may also want to consult primary and secondary sources depending on your assignment.
Personal interviews may not necessarily be an accurate description of events. Each witness may have a different perspective on the event. Personal emotions, self-identity, or community values may influence perspectives. Consider, for example, when law enforcement officers interview witnesses at the scene of a car accident. Do all witnesses report the same sequence of events? Should as many personal accounts as possible be gathered in an attempt to reconstruct the accident?
