Representative statement: Hellyer has stated that "UFOs are as real as the airplanes flying overhead" and that governments have covered up evidence of extraterrestrial visitations.

Hellyer's high‑profile status gives his claims significant media attention. Critics question his evidence, while supporters see him as a courageous whistleblower.

Hellyer remains an influential voice in the UAP disclosure movement, particularly in Canada and internationally.
