There is plenty of evidence that a small % of these sightings are Alien spacecraft. A fact publically stated by : Lord Dowding RAF Chief, Lord Hill Norton Chief NATO, Prof Poher + Pro Hyneck frnch & US gvt UFO projects, Adml Hilenkoter CIA chief - The evidence is available - see COMETA report

andrew moore, brighton,

ln the Middle ages the people bellieved in Witchcraft,the victorian had there fairies,we have our Aliens,funny we dont seemed to have moved on

KENNETH BOWRY, LONDON, MIDDLESEX

Its not funny . Ive been abducted forteen times and each time they released me my nether parts were very sore. I dont know what they do to me ? but I am moving house and hope they wont find me. Those space men have no respect for earthlings.

If I was an ET on vacation & passed within the vicinity of Earth. I would most likely pass on the opportunity of a 'stop & see' as a quick check of my Baedeker equivalent would warn that I stood a high chance of dying under a hail of civilian gunfire. Maybe that's why Earth is not a popular spot?

Willam Edwards, Chesterfield, England

The greatest evidence there is of the existence of intelligent alien lifeforms, is the fact that they have chosen NOT to contact us!

Dilip Dhokia, Bradford, UK

It is no great wonder they have never visited since this planet lacks intelligent life.

'HM Government has never been approached by people from outer space'

Rather surprising - from the looks of the present lot, I would have thought they were all from out of space !

Probably RAF Harrier jump jets or helicopters,or somebody
playing with a frisby.
Seems to me that it is always the same people that see them,rather strange.

David Nigel Braham, Milan, Italy

Its easy to put all UFO discussion in the 'fruitcake' section. I personally have a very hard time believing abduction stories, but at the end of the day, what did the police in Edgeware see in April 1984? Either our senses are prone to malfunction en masse or there still are inexplicable phenomena

Kev Wilson, Slough,

You earthlings!

Stephen robertson, Newcastle upon tyne, Earth

Impossible or not, technically unfeasible or not, believable or not, doesn't really matter. Once you have seen one, you have seen one and that's that! And yes, I've seen one (very large slow flying triangle - along with dozens of other people) I haved no idea what it was so it's UFO so there!

Steve, London, UK

Kim..yeah abit like Columbus. He was actually the 2nd person to discover America. First time it was hushed up .!!!!....Only joking, a big hello to all our Allies.

kirk, Rotherham, UK

It is strange how people who see UFOs always know they are space craft of extraterrestial origin.

If you can identify what a flying object is, it is not a UFO is it.

Keith S, Winnipeg, Canada

Ditto to Mike in China.

kevin, Boring, Oregon

Well I have seen some Mike, but no one will believe me.

Tone, Sydney, Oz

Alien life.....I've met many people in my life...I've always thought some were from another planet......

Ahmed, Bristol,

Why no mention in reported sightings of the UK's most famous, tantalising and unresolved UFO case witnessed by civilians, police and military in Rendlesham Forest / Woodbridge, near Ipswich, Suffolk in Dec 1980. Apparantly the video footage of the incident was hidden away. Will that be released now?

Michael Lewis, St Albans, Herts

Larry, you misread what's said, it said the difficulties were stunning, not impossible. Remember it has taken from the dawn of civillisation to get this far, inter-stellar travel may happen, but it's going to take some time yet. For a start a power source needs to be developed that could cope.

T. Hamilton, Chatham,

Interesting, though I always wonder why there's so few video/photo records of UFO or they are of such poor quality? One of the latest clear-cut videos was shot in Sevastopol, Ukraine.

Jan, Kyiv,

I don't know what all the fuss is about.
I've disappeared twice in the Bermuda Triangle and been abducted by aliens once.

John Redwood, newport, Wales

Aircraft from Area 51 are often in the skies. Has anybody seen Aurora lately? General Kammler must be laughing too!

Charles Morgan , Madrid , Spain.

Hmmm...
If you have not seen an Unidentified Flying Object, no one could convince you they exist. If you have seen dozens of them the past 50 years, you would know there is more to it than meets the eye.
By observation, I know that UFOs exist. The only unknown is their point of origin...

Dakota Clark, Lake Stevens, Washington, USA

I'd just settle for intelligent life existing here.

Mike, Macau, China

".. the technical difficulties in inter-stellar travel are stunning"

When will the masses learn? Just because an old man in blue jeans SAYS it's so - doesn't MAKE it so. If you haven't witnessed an event - that doesn't prove it's impossible.

Remember when the speed of sound was a 'brick wall'?

Larry, Middletown,

These space visitors zoomed over earth, saw what a lousy job we are doing down here and went home!
