Disdain, confusion around officials’ handling of UFO reports

Reviewed by Chris Rutkowski 4 minute read Saturday, May. 21, 2022

Although the subject of unidentified flying objects (UFOs) is very popular and has persisted since the 1940s — when the darned things were known as flying saucers — skeptics often note that few academic or scholarly studies on this topic have been produced.

Search for the Unknown: Canada’s UFO Files and the Rise of Conspiracy Theory, based on the excellent doctoral dissertation by Canadian historian Matthew Hayes at Trent University, challenges that assertion. In this way it’s similar to David Jacobs’ 1973 history thesis The UFO Controversy in America, from the University of Wisconsin.

Hayes’ in-depth, heavily annotated work is not, however, a book about UFOs. In fact, Hayes only describes three Canadian UFO cases in detail and briefly notes a few dozen others.

Hayes instead “presents a history of the Canadian government’s investigations into reports of UFOs, and how these were handled, handed off, and defended from 1950 to the 1990s.”

New book debunks Winnipeg-lab coronavirus conspiracy theory

CBC News 1 minute read Tuesday, Aug. 31, 2021

A new book concludes co-operation between Canada's National Microbiology Lab in Winnipeg and China's Wuhan Institute of Virology played no part in the origin of the coronavirus pandemic but raises questions about links between one of the researchers fired from the lab and a prominent Chinese virologist affiliated with the military.

Toronto-based freelance journalist Elaine Dewar says she set out to investigate the hypothesis that the coronavirus was leaked from the Wuhan lab by looking at the science and financial and geopolitical interests related to the theory.

As part of that, she looked into whether an approved shipment of Ebola and henipah viruses in March 2019 from the Winnipeg lab to Wuhan had anything to do with the pandemic after conspiracy theories suggesting it did surfaced online.
