Over the past two weeks, a number of mysterious objects have been shot down from the skies over the US and Canada. It all began with a suspected Chinese spy balloon, which was brought down off the coast of South Carolina on 4 February.

Meanwhile, the diplomatic rift between China and the US is widening.
Megan Gibson in London, Ido Vock in Berlin and Katie Stallard in Washington DC discuss the spy-balloon fiasco, aliens, and where US-China relations go from here.
