I participated in a radio show on WHAM Rochester NY and other smaller stations where we discussed ufo's and also belonged to a witness group subject to hypnosis interrogations. I met many of the pioneers so after talking to literally thousands of people including military, I had formed a solid opinion but admitted I had no hard evidence. Separating the frauds from the truthfully sincere was easy.
I did not want a career in the field to cloud my judgement so now at long last the truth I knew has been affirmed which is satisfying but still empty of substance. I don't think the pervasive silence from 'above' will change in my lifetime. I think they are smart to have been quiet but obvious for the last couple hundred years.
