An Air India plane that was flying to Chicago had to land in a place called Iqaluit in Canada because someone said there was a bomb on the plane.
The plane landed safely, but everyone had to get off and wait for the airport to check everything carefully.
There was a big argument between Canada and India, so this made people even more nervous.
The plane was checked and everyone was safe, but it took a long time before the plane could fly again.
