On Wednesday the Pentagon released a selfie taken by a US pilot showing the Chinese spy balloon in the air before it was shot down days later.
The photo shows the shadow of the aircraft on the balloon, which was floating at 60,000 feet when it was spotted over Montana.
It also shows a clear image of the balloon’s payload as it crossed across the continental US.

The balloon was first spotted by the US on January 28 and ultimately shot down by the US military off the coast of South Carolina.
Investigations began immediately after the balloon was retrieved from the Atlantic Ocean earlier this month.
Pieces of the debris were transferred to the FBI Laboratory in Virginia to be studied further.
