Third UFO is shot down over North America in 3 days after ‘threats’ over Lake Huron, Canada & Chinese ‘spy’ balloon

UFO panic is sweeping the US after three unknown objects were blasted out of the sky in 72 hours.

Pentagon officials have swung into action over the last week after the flight of a gigantic Chinese spy balloon over the US.

Since the enormous blimp was blasted out of the sky on February 4, three more "objects" have since been downed by fighter planes.

Strange accounts have been given by the fighter pilots, including reports the objects interfered with their sensors and had no recognizable propulsion.

The mystery is deepening as limited information has been released on the shootdowns - with China also playing dumb and denying any knowledge.

And to muddy the waters further, Beijing claimed it had detected and was preparing to shoot down its own mystery object on Sunday.

China said the object had been flying close to a base for their nuke submarines.

The objects right now can be considered "UFOs" - as they remain in all sense of the term unidentified.

US Air Force General Glen VanHerck gave cryptic responses to reporters' questions - refusing to rule out anything, including aliens.

He said they did not know what the objects were - or how they stay aloft in the sky.

"We're calling them objects, not balloons, for a reason," the general, who is the head of North American Aerospace Defense Command, said.

"I'll let the intel community and the counterintelligence community figure that out."

But while his comments on potential extraterrestrial origins caused a stir, defense officials have since downplayed the possibilities the objects could be alien.

The military has not seen any evidence that the objects were extraterrestrial, a defense official told Reuters.

• February 12 - US fighter planes shoot down the Montana object over Lake Huron
• February 12 - China claims it detected an unknown object over the Yellow Sea and near to nuke sub base

The latest shoot-down occurred after the object was first detected on February 11.

It was initially dismissed as a radar glitch, before then being detected again after going near sensitive military sites.

The US scrambled an F-16 fighter plane which blasted the object out of the sky at 20,000 feet over Lake Huron, Michigan.

The object was described as "an octagonal structure with strings hanging off but no discernible payload."

"Based on its flight path and data we can reasonably connect this object to the radar signal picked up over Montana, which flew in proximity to sensitive [defense] sites," said a statement from Norad.

"We did not assess it to be a kinetic military threat to anything on the ground, but assess it was a safety flight hazard and a threat due to its potential surveillance capabilities."

It comes just one day after Canadian Prime Minister Justin Trudeau confirmed another "object" was shot by US officials over Canada.
