More flying objects shot down

American fighter jets shot down two more unidentified objects over the weekend; one over the Yukon in Canada on Saturday and the other high-altitude object was shot over Lake Huron in Michigan on Sunday.

On Friday, an object the size of a small car was taken out by the US military off the coast of Alaska.

So far, four unidentified objects have been taken out by the US over North America, raising questions for the top military brass as well as the US spy agencies. 

Whose are these?
Though the first balloon was a suspected Chinese spy balloon to intercept communications, officials are not sure what the other three are.

So far, no link to Chinese surveillance has been established. The airborne objects were taken out as they posed a threat to civilian air traffic.

NORAD and Canadian forces are working to recover the wreckage and analyze it.
