It may have ticked all the cliche boxes - saucer-shaped, bulge in the middle, metallic - but no one has yet stepped forward to explain the slow-moving object.
The incident came right at the close of last Friday's spectacular at the Olympic Park stadium in Stratford, east London at around 12.30am.
And it was just as Nick Pope, one of the UK’s top UFO experts, predicted only weeks ago - that mass summer events would be a prime time for crafts from other worlds to present themselves to mankind.

This UFO was seen at the Olympics opening ceremony in Stratford, east London
EnlargeOne theory is that the 'spaceship', whose presence was reported by Examiner.com, was a blimp used by a news channel to gather footage.

But while NBC Olympics - a division of NBC Sports - has picked Goodyear blimps for all of its 2012 Olympics aerial coverage, the object does not look like one of the floating airships.
Some commentators on YouTube believe it is actually a helicopter - or simply a fake.
Mr Pope, who worked at the Ministry of Defence for 20 years, investigated reports of UFOs between 1991 and 1994.
One theory is that the object was a blimp or helicopter used to gather aerial footage
Aliens may be visiting Earth for military reconnaissance, scientific research, or just to enjoy the scenery and partake in some tourism
SO WHAT WAS THAT IN THE SKY?
Here are some of the theories regarding the Olympics UFO...
- A blimp (above)
- A helicopter
- A fake
- Or simply an alien spacecraft
Speaking earlier this month, he said: 'It has been a widely held belief in Ministry of Defence circles that "aliens" have been able to detect us for decades via TV and radio broadcasts.
'What once seemed like science fiction is steadily being realised by central governing bodies as distinctly real.
'If aliens have studied our psychology, they may choose to appear in our skies on a significant date.
'The closing ceremony of the Olympic Games is one date being widely circulated by conspiracy groups.’
The footage is believed to have originated from a web user known as 'MrScipher'.

Tony Blair and the 'UFO cover-up'Two weeks ago, it was revealed that former prime minister Tony Blair received a briefing about UFOs from the Ministry of Defence because of his concerns over the disclosure of classified information on alien life-forms.
Downing Street requested the advice for the PM in 1998 as the Freedom of Information Act was being introduced, which allowed the public to obtain information on alien mysteries.

According to The Daily Telegraph, Mr Blair sought advice from the MoD for its policy on the issue.
He was told by staff at the ministry that it has 'only a limited interest in UFO matters' but that they ' remained open-minded' about 'extraterrestrial life forms'.
Details of the briefing emerged ahead of a release of files on July 12 by the Government of more than 6,700 pages detailing seemingly close encounters with UFOs over the last 30 years.
Among a series of UFO sightings in the files is a policeman's report of a mystery cluster of lights darting across the sky during an FA Cup replay between Chelsea and Manchester United.
The mounted officer's claims to have seen the bright object hovering over Stamford Bridge in March 1999 for almost 15 seconds, slowly changing shape, were corroborated by a colleague.
The ‘credible witness report’ is one of a series investigated by the Ministry of Defence, whose top-secret files are being released in sections by the National Archives following the closure of the ministry’s UFO desk in 2009.
One confidential 1995 report by the defence official responsible for manning the desk says the presence of extra-terrestrial lifeforms is ‘possible’, although there is ‘no direct evidence’.
It also speculates on the reasons why aliens may be visiting Earth, including for military reconnaissance, scientific research, or just to enjoy the scenery and partake in some tourism.
The policeman claimed that he saw something ‘unlike anything I’ve seen before’ at Stamford Bridge while Manchester United beat Chelsea 2-0 in the FA Cup quarter final replay.
Another file describes a West Wales hotelier who saw a UFO landed in a field. Two ‘faceless humanoids’ in silver suits emerged and took measurements.
