The latest episode of The Walking Dead season seven introduced viewers to new character Jadis (Pollyanna McIntosh) and her mysterious faction - not to mention one of the most insane walkers the series has seen - however, one scene left fans scratching their heads after spotting what they thought was a huge mistake.

The moment in question occurred when Rick (Andrew Lincoln) got taken to the “up up up,” the apex of a huge pile of rubble situated in a large junkyard where Jadis' people - branded The Scavengers by fans - reside.

The backdrop, which was achieved using green screen, saw something fly past Rick's head in the distance, many believing it to be a plane which would be quite a big revelation considering the series takes place in a zombie apocalypse.

While making viewers look twice, the moving object is clearly not a plane or UFO, but a bird - not a stretch to imagine considering birds would likely be hanging around scrapheaps.

So no, don't expect Negan to unveil a surprise plane in a future episode, and don't get excited for a Fear the Walking Dead crossover.
