The first sighting was made by me n friend disc shape craft numbering over 50 in sky and hovering over water seems to move in unisun as if in search pattern seems to communicate by flashing white n red lights to each other distemces varied from 50ft to miles craft over water seems to be in groups of 3 and moved miles at blink of eye direction changed without slowing or stopping path which higher ones flew was erratic appears to shake side t side sometimes when hovering and shown red and white beams into water and over island of sanda as if looking for somthing n shot across sky from standing start without taking time to speed up seemed to join toghether to make large triangle craft which when got close emitted humming buzz like power station but u could feel the noise and static in air sighting lasted 5 hours and had me and friend amazed at first then terrified later at sheer numbers of craft we thought the world was under attack craft over water went into sea as light came up ones in sky dissapeard when we first saw the objects we thought they were drones till we seen the speed and ease of movement it was the weirdest thing i have ever seen from my caravan window and i lived there for a year before this.2nd sighting.Was of one disc made around a week later by me and my girlfriend in the same location moving erratic thru sky at speed lasted only minutes. 3rd sighting same local only several craft doing same as first sighting made by only me around 2 weeks after first the last was made by myself and 3 other van owners and went on all night again only different from first sighting was craft in water working with 3 above seems as though ones above would do search pattern then join up with one under water craft the ones above would shine down white beam which would join red beam from craft under water then repeat process over n over all night i got opinion they were fishing or building something under water but amount of craft was over 100 again
