Air Crash Investigation, also known as "Mayday: Air Disasters". It's a Canadian production that airs in several countries. In the USA some episodes are shown in the block "Air Emergency".

1. In ancient times the Rings of Power were crafted by the Elven-smiths, and Sauron, the Dark Lord, forged the One Ring, filling it with his own power so that he could rule all others. But the One Ring was taken from him, and though he sought it throughout Middle-earth, it remained lost to him. After many ages it fell into the hands of Bilbo Baggins, as told in THE HOBBIT. In a sleepy village in the Shire, young Frodo Baggins finds himself faced with an immense task, as his elderly cousin Bilbo entrusts the Ring to his care. Frodo must leave his home and make a perilous journey across Middle-earth to the Cracks of Doom, there to destroy the Ring and foil the Dark Lord in his evil purpose.

A mysterious group of ninja called the Sora-nin from the Sky Country makes a surprise attack on Konoha. This is because Konoha nearly destroyed the Sky Country during the last Shinobi World War. However, they survived and now are after Konoha and the Fire Country for revenge.

The group starts attacking Konoha causing mass mayhem, with flying ninjas on winged-mechanical devices bombarding the village. A boy comes all the way to inform Konoha that his village had been attacked and he was looking for his sensei, who was currently in Konoha, to go with him to heal the injured at his village.
