UFOs in the daily Press:

UFOs sighted in Beijing sky

Monday between 7:00pm and 9:00pm [April 22], many Beijing residents were startled to spot four spiraling and sparkling unidentified flying objects (UFOs) in the evening sky near Asian Games Village, Wa Li and Qing He. Over 10 readers called local media about the strange appearance, Beijing Times reported.

At about 8:00pm, four sparkling UFOs appeared in the southwest sky, but no strange noises accompanied them, according to observations of one reporter.

These unknown UFOs moved across a wide range and were surrounded with a kind of light yellow brightness.

According to a reporter's estimates, they were flying at about 10 kilometres high. For most of the time the objects were visible, they moved in two groups of two.

At about 9:00pm, the UFOs disappeared under gradual cloud cover.

The UFOs attracted many people, with most saying they had never seen such strange things.

Though there are piles of reports about unknown flying objects from home and abroad, nothing has yet been proven, according to the deputy director of Beijing Planetarium surnamed Zhang.

There has never been an official conclusion providing a scientific explanation for UFOs, according to Zhang.

Over the last hundred years, there have been more than 10,000 records of UFO sightings, according to Lan Songzhu, engineer of Xinglong Observation Station of Beijing Astronomical Observatory.

About 95 per cent of these sightings have been shown to be phenomena related to astronomy, atmospheric or the globe magnetic field. There is still no proof of the existence of extraterrestrial life, noted Lan.

Lan said there UFOs come in four types. One is the appearance of satellites, dust storms, meteor rains or sparkling clouds. The second kind of UFO can be broken piece of a flying object. The third can be big throngs of locust or butterflies. The last can be planes.
