Of all of the UFO sightings and encounters on record, very few can claim to have been witnessed by more than a few people at a time at best. These are typically very isolated incidents, seen by only small groups of people at most, and this has only further served to generate doubt on the part of skeptics or for those who place no veracity on UFO phenomena as a whole. Yet, every once in a while, there are truly spectacular cases of mass sightings that get plenty of documentation and exposure. Although rarer than most accounts, such mass sightings typically provide a rich variety of witnesses, many of them often very trusted people in social high standing, or professionals, trained personnel, and experts. They often serve to be harder to explain away than typical sightings, and usually earn their place among the more bizarre UFO accounts.
