Bender ran an organization called the International Flying Saucer Bureau (IFSB) a small UFO organization based in Connecticut, USA and he also edited a publication known as the Space Review which was committed to the dissemination of news about UFOs. In truth, the organization had only a small membership and the publication circulated amongst hundreds rather than thousands, but that its members and readers valued it was in little doubt. The publication itself advocated that flying saucers were spacecraft of extraterrestrial origin.
However... in the October 1953 edition of Space Review, there were two major announcements.
A source which the IFSB considers very reliable has informed us that the investigation of the flying saucer mystery and the solution is approaching final stages. This same source to whom we had referred data, which had come into our possession, suggested that it was not the proper method and time to publish the data in 'Space Review'.
The mystery of the flying saucers is no longer a mystery. The source is already known, but any information about this is being withheld by order from a higher source. We would like to print the full story in Space Review, but because of the nature of the information we are very sorry that we have been advised in the negative.
We advise those engaged in saucer work to please be very cautious.
Bender might very well have known “what the flying saucers” were, at least a portion of them... but he later revealed in a local newspaper interview that he was keeping his knowledge a secret following a visit by three men who apparently confirmed he was right about his Unidentified Flying Object theory, but put him in sufficient fear to immediately close down his organization and cease publication of the journal.
It has been argued that the story of being visited by three strangers and being warned off was a front to close a publication that was losing money, however the fact that Bender had been “scared to death” and “actually couldn’t eat for a couple of days” was verified by his friends and associates. It is also widely known that such “stories” are often spread by the United States, and other governments to discredit those who might just have the truth, or at least a portion of it.
In 1963, a full decade after his visit from the three strangers, Bender was seemingly prepared to reveal more of his story in a largely unreadable book entitled Flying Saucers and the Three Men in Black. The book was scant on facts, however, it described extraterrestrial spacecraft that had bases in Antarctica.
This was apparently the truth Bender was terrorized into not revealing.
