at the mutual ufo network (mufon), we’re deeply involved in unraveling the enigmas of the cosmos, from ufo sightings to alien abductions and the formation of crop circles. unlike enigma labs and the national ufo reporting center (nuforc) who also take reports, mufonactually investigates into unidentified aerial phenomena (uap). we provide a platform for experiencers and ufo abductees to report a ufo or report an alien abduction. our ufo database is a comprehensive collection of information, encompassing reports of flying saucers, ufo crashes, and even cattle mutilations linked to ufo activities. we also run a popular ufo podcast and an annual ufo conference. at mufon, we’re not just bystanders; we’re active contributors in the realm of ufo investigation and ufo reverse engineering. so, whether you’re a pilot who’s had a ufo encounter or someone intrigued by the unidentified aerial phenomena, mufon is your ultimate guide.
