A new high-altitude flying object shot down over Northern Canada, Prime Minister Justin Trudeau says

Canadian Prime Minister Justin Trudeau said Saturday that on his order a U.S. fighter jet shot down an “unidentified object” that was flying high over the Yukon, acting a day after the U.S. took a similar action over Alaska.

North American Aerospace Defense Command (NORAD), the combined U.S.-Canada organization that provides a shared defense of airspace over the two nations, said it had detected an object flying at a high altitude over northern Canada. It wasn’t immediately clear how high up it was flying or what it was.

Trudeau said he also spoke with President Joe Biden, who himself ordered the downing of an unidentified object over remote Alaska on Friday.

“Earlier today, President Biden spoke with Prime Minister Trudeau on the unidentified, unmanned object in North American air space,” according to a statement from the White House. “The object was closely tracked and monitored by North American Aerospace Defense Command (NORAD) over the last 24 hours and the President has been continually briefed by his national security team since the object was detected.”

Both Biden and Trudeau authorized shooting down the object both “out of an abundance of caution and at the recommendation of their militaries,” the statement said. 

“A U.S. F-22 shot down the object in Canadian territory using an AIM 9X missile following close coordination between U.S. and Canadian authorities, to include a call today between Secretary of Defense Lloyd J. Austin III and Minister of Defence Anita Anand, according to Pentagon Press Secretary Brig. Gen. Pat Ryder. “As Canadian authorities conduct recovery operations to help our countries learn more about the object, the Federal Bureau of Investigation will be working closely with the Royal Canadian Mounted Police.”

A NORAD spokesman, Maj. Olivier Gallant, said the military had determined what the object was but would not reveal details.

F-22 fighter jets have now downed three objects in the airspace above the U.S. and Canada over seven days, a stunning development in the skies that is raising questions on just what, exactly, is hovering overhead and who has sent them.

At least one of the objects downed was believed to be a spy balloon from China, but the other two have not yet been publicly identified. Trudeau said that Canadian forces would recover the wreckage for study. The Yukon where it was shot down is the westernmost Canadian territory and the among the least populated part of Canada.

The downing came a day after White House National Security Council spokesman John Kirby said an object roughly the size of a small car was shot down in remote Alaska. Officials couldn’t say if it contained any surveillance equipment, where it came from or what purpose it had.

Kirby said it was shot down because it was flying at about 40,000 feet (13,000 meters) and posed a “reasonable threat” to the safety of civilian flights, not because of any knowledge that it was engaged in surveillance.

According to U.S. Northern Command, recovery operations continued Saturday on sea ice near Deadhorse, Alaska.

In a statement, the Northern Command said there were no new details on what the object was. It said the Alaska Command and the Alaska National Guard, along with the FBI and local law enforcement, were conducting search and recovery.

“Arctic weather conditions, including wind chill, snow, and limited daylight, are a factor in this operation, and personnel will adjust recovery operations to maintain safety,” the statement said.

Last Saturday, U.S. officials shot down a large white balloon off the coast of South Carolina.

The balloon was part of a large surveillance program that China has been conducting for “several years,” the Pentagon has said. The U.S. has said Chinese balloons have flown over dozens of countries across five continents in recent years, and it learned more about the balloon program after closely monitoring the one shot down near South Carolina.

China responded that it reserved the right to “take further actions” and criticized the U.S. for “an obvious overreaction and a serious violation of international practice.”

The Navy continued to survey and recovery activities on the ocean floor off South Carolina, and the Coast Guard was providing security. Additional debris was pulled out Friday, and operations will continue as weather permits, Northern Command said.
