Mystery surrounds how 62 children claim they saw a UFO landing outside their school.
Three decades ago the pupils claimed they saw a disc-shaped craft land from the sky and stop in a field outside their school in Zimbabwe.
The case has fascinated UFO enthusiasts because of the large number of witnesses who all claim to have seen the same thing.
Most UFO sightings tend to occur in the West and this one in Africa also helped garner more of the world’s attention when it happened.
Even 28 years after the incident happened many of the children maintain that they did see a UFO on September 16, 1994.
The witnesses have been given the chance to tell their side of the story in a new documentary film called Ariel Phenomenon.

But many doubt whether the children did see an alien spacecraft and say that the claims are simply a case of mass hysteria spreading.
In the documentary the now grown up children offer their testimony as to what they saw.
They also describe their battle to be listened to and believed as they were doubted along the way.
Speaking to The Sun, the film’s director Randall Nickerson explained that the witnesses must have their chance to be heard and not have their experience dismissed.
Nickerson said: "We have to be able to be truthful about people's experiences and say 'well, maybe we don't understand what is going on.
“It is necessary at this point, we are seeing more and more as our technology develops.
“It is something we have to have a conversation about and explore - and Ariel is a big part of that.”
The children at the rural Ariel School were having their morning break when the incident happened.
Teachers at the school were having a meeting inside at 10am and not around to bear witness to the event.
The former pupils recalled that the landing took around 15 minutes and they saw an object lower from the sky onto a field behind the school’s playground.
Immediately some of the children ran away as they watched the craft land.
Others claimed that they saw alien human-like creatures leave the craft which the witnesses described as being shaped like a silver disc.
After the alleged sighting, news of the incident spread and was covered by BBC War Correspondent Tim Leach.
The children were aged between six and 12 when they gave their accounts of what happened on the day.
Psychiatry expert Dr John Mack of Harvard University heard about the event and wanted to interview the witnesses.
After speaking to the children Dr Mack concluded that their accounts were credible.
The children reported seeing at least one UFO and alien figure and even made drawings of what they saw.
Some even suggested the figures could have been folklore creatures rather than aliens.
UFOs have been in focus around the world for many years now and events such as the Roswell incident in America in 1947 are still debated today.
The 1994 alleged UFO sighting in Zimbabwe adds to the growing list of potential alien sightings and could be a key moment in mankind’s search for extra-terrestrial life.
