Bill Chalker is one of Australia’s leading UFO researchers and the author of The OZ Files: The Australian UFO Story and Hair of the Alien: DNA and Other Forensic Evidence of Alien Abduction.

Bill's personal 'top ten' regional Australasian case list...

1. 31 August 1954 Sea Fury case, near Goulbourn, NSW, Australia (experienced naval pilot, radar visual confirmation, independent ground witnesses, apparent intelligent responses to witnesses’ thoughts about possible collision)

2. 23 July 1992 Peter Khoury “Hair of Alien” DNA case, Sydney, Australia (abduction-type encounter with female Nordic blonde yields anomalous hair sample that suggests “hybrid origin” and unusual genetic profiles)

3. 27 June 1959 Father Gill UFO entity sighting, Boianai, Papua New Guinea (credible multiple-witness sighting of animate entities on UFO with intelligent interactions)

4. 30 September 1980 George Blackwell’s UFO landing and physical trace case, Rosedale, Victoria, Australia (compelling array of physical evidence – ground trace, missing water, effects on witness, other witness)

5. 8 August 1993 Kelly Cahill’s abduction experience, Narre Warren North, Victoria, Australia (possible independent multiple-witness UFO encounter with abduction aspects and physical evidence)

6. 19 January 1966 George Pedley’s UFO nest encounter, Tully, Queensland, Australia (daylight close encounter with UFO take-off leaving physical evidence – “UFO nest”)

7. 14 April 1966 Ron Sullivan’s “bent headlight beam” experience, Burkes Flat, Victoria, Australia (striking UFO encounter, physical traces, bent light beams, possible related fatalities)

8. 6 April 1966 Westall school daylight UFO landing encounter, Westall, Victoria, Australia (multiple-witness daylight landing, physical traces, “cover-up” dimensions)

9. 1977–78 Gisborne UFO abduction milieu, Gisborne, New Zealand (complex and high strangeness UFO and abduction milieu – entities, multiple witnesses, multiple abductions)

10. May – August 1973 Tyringham Dundurrabin intense UFO flap area, New South Wales, Australia (long-term intense UFO flap, multiple witnesses, physical effects, paranormal aspects)

Jenny Randles has investigated UFOs since 1974 and was BUFORA’s Director of Investigations for 13 years. She is the author of more than 50 books on strange phenomena.

Here is her top ten UFO cases list :

1. Sept/Oct 1947, Himalayan Foothills, Tibet. Multiple witnesses encountered a daylight rotating mass that induced physical illness and skin rashes on their bodies.

2. 24 May 1964, Burgh Marsh, Cumbria. Fireman and his family having a picnic and photograph a ‘spacesuit’ garbed figure not seen at the time. Possibly a hoax, but a fascinating as yet unresolved detective story.

3. 1 July 1965, Valensole, France An egg-shaped object that landed in a lavender field with small humanoid entities getting out. Subsequent long-term physical effects on the crop.

4. 2 Nov 1968, SE France A family including a highly respected scientist and his young child, who experienced a close encounter with a UFO and light beams that produced both rejuvenating effects on physical injuries and left recurring skin marks on the body.

5. 19 Sept 1976, Tehran, Iran A midair encounter involving a fighter jet scrambled to pursue a UFO that was witnessed by people on the ground in multiple locations. The aircraft suffered unusual electrical interference as it attempted to fire an air to air missile at the target.

6. 9 Mar 1977, Nelson, Lancashire Two men in a car in the early hours and a large dark cigar shape that descended from clouds, stalling the car engine and lights and creating severe physical effects on both witnesses until it moved out of range.

7. 6 June 1977, Barnard Castle, Durham A motorcyclist and a car driver both suffered impedance of their vehicles as a glowing purple mass floated next to them during heavy rain. All surface water was instantly evaporated from the bike and leather clothing, and the cyclist suffered long term physical illness.

8. 17 Sept 1977, Newmill, Cornwall A young couple saw a green hazy mass that floated towards them only inches off the ground. They were subsequently struck down by severe physical effects (headaches, muscle pains and severe vomiting) and had to be hospitalised while doctors struggled to find any cause. Both recovered from the mystery illness, but this sort of case seems to offer a genuine challenge to the sceptics and, I suspect, is caused by a highly energetic and rare atmospheric phenomenon.

9. 13 Mar 1980, Haselor, Warwickshire A glowing object passed directly across the path of a car, apparently triggering excessive heating within the steering wheel. Study of the physical forces involved offer useful data about the energy levels and physical processes.

10. 26 Dec 1980, Rendlesham Forest, Suffolk The initial close encounter in the forest involving three USAF personnel remains unresolved. It features a close proximity encounter with intriguing physical effects and altered states of consciousness reported.
