The aircraft was an American made plane owned by an Irish company, not a Russian one, and was supposedly well maintained, according to its records. Now reports are saying that the pilot never complained about it and did not make a distress call, but that the plane broke up in midair. Bodies are being recovered over a five mile radius.
Isis released a video (shot from the ground at a distance, it looks) showing a large plane apparently exploding in the middle and then plunging downwards with a huge trail of smoke. They claim it was a missile, but it’s not thought they can reach that high, so some authorities are now suggesting that there was a bomb on board.
The Airbus A321 is not made in the US.
