I'll admit that I am skeptical of Bob Lazar's story. In the interviews I have seen of him, his knowledge of physics isn't on par with what I would expect for someone to have been brought into a black project UFO program for reverse engineering. But, who knows. A lot of crazy decisions have been made over the years.
Lazar's disclosure is a good rubuttal to people who claim that if it is true the government would not have been able to keep it secret all of these decades. If it is true, it hasn't been kept secret. In addition to Lazar, over the decades other people also have come out claiming to have worked in the UFO reverse engineering program. Whether they should be believed is another matter but, if it really exists, the veil of secrecy has not been as effective as some like to pretend.
In the past, campaigns against the credibility of witnesses have been very effective at keeping the UFO topic relegated as being crazy talk from hoaxsters, opportunists and crazy people. Further attempts to do so occurred just this week:
After the release of the Harald Malmgren interview yesterday where he delves into the UFO topic, there was pressure to remove his biography from Wikipedia. Wikipedia even held a request for comments on the issue. As of today the page still is up, but a whole lot of edits to the page were made this morning:
https://en.wikipedia.org/w/index.php?title=Harald_Malmgren&action=history.
Yesterday, though, Christopher Mellon's biography was deleted from Wikipedia.
https://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Christopher_Mellon. The fact it happened on the day the Malmgren interview was released is not a coincidence. I have no doubt in my mind the motivation behind the deletion was his involvement in the UAP topic.
Regardless of those shameless attempts to censor UAP information, smoke around the topic continues to build. The shear number of people coming out of very high positions in the U.S. government who are telling us UFO phenomena are real is significant. There also were tussles in Congress that gutted the original UAP Disclosure Act, there has been a congressional investigation of the UAP topic underway for the past couple of years, and the military and intelligence agencies have continued to resist the release of information they have on the topic.
What is the truth on the matter I do not profess to know, and I am very skeptical of much of the UFO lore. But, I find the topic to be interesting, especially the struggles over transparency going on behind the scene, and I am curious to see how it evolves.
