On Aug. 20, a huge glowing bubble-shaped floating object was spotted in many cities in China.
Some witness claimed that the glowing object grew bigger and bigger as time passed. "It was several hundred times bigger than the moon, with a diameter of more than 50 nautical miles. About 20 minutes later, the shining bubble became darker and gradually disappeared," one witness said.
On Aug. 20, a pilot of China Southern Airlines posted on the microblog that the unidentified flying object was more than 10,000 meters above Shanghai when it was spotted. He said he was in the cockpit when he saw the object. Later his post was followed and forwarded by many internet users.
"It was so big and so round! At first I thought it was just an illusion, but the copilot asked me whether I have seen the bubble too," the pilot said, "At least 10 pilots in this area reported the object to the air control traffic bureau when I reported it."
Besides in Shanghai, some amateur astronomers and netizens in Beijing, Inner Mongolia Autonomous Region and other cities also spotted the glowing bubble about the same time as the Shanghai sightings.
