I have seen many similar presentations; Bigelow included.

If you watch the documentary "Unacknowledged" (2017, Dr. Greer) , there are 20-30 different well documented experts, letting the world know about what they worked on, and sounds similar to Bigelow in many ways.

One person is one person.

When 25 people come out and want to expose what they were involved in, what they know about this subject, it becomes very impressive.
