A new scathing review of the current state of ufology by veteran Spanish ufologist Vicente-Juan Ballester Olmos is at link below:

(For anyone not familiar with his name, Vicente-Juan Ballester Olmos is a Spanish UFO researcher with over 30 years of experience in this field. He is the author of several UFO books, with forewords written for him by Dr. J. Allen Hynek, Dr. Jacques Vallée, and Dr. Richard Haines. As I wrote in an item about a decade ago, V-J's name isn't as well known on English/American discussion forums as he deserves, partly because he is Spanish and his first language is not English. There is a definite tendency in the English-speaking UFO community to focus on the work of researchers in English speaking countries. Also, V-J avoids sensationalism. Researchers that make more sensational statements gain more attention - whether their work deserves it or not...).

VJ's rather damning comments in his new article at the above link include:

"In the 1950s charismatic UFO organizations were established, only to close down decades later without having achieved their main objective, to prove that flying saucers exist. Nothing extraordinary or persuasive was transmitted, only thousands of “UFO journals” pages filled with stories and lots of cabinets with innumerable cases files destined to yellow with the passage of time. Nowadays, private centers devoted to the “study” of UFOs can be counted on one hand’s fingers. The healthiest-funded one, set up in Sweden, is mainly dedicated to preserve UFO archives, well aware of the increasing number of retiring ufologists, abandoned files, and shut down organizations." ...
and

"Ufology not only fails to advance, it is a vicious circle. Today we see UFO news publicized on the internet with the same old images of lens flares or aircraft contrails that seemed strange in the 1950s. Because there are no academic or authoritative criteria universally accepted, and no hard evidence that exists as a certainty, past mistakes recur over and over. Ufology is immersed in a loop that never ends".
