Out front next, a fatal error. A U.S. official telling CNN that Russia may have confused

the passenger jet that crashed for Ukrainian drone, as we hear from passengers who survived

Plus a second stowaway on a second Delta flight. This time the person was caught just minutes before takeoff.

So how does this keep happening? And breaking news, President-elect Donald Trump tonight with a last-minute

That is according to a U.S. official.

Video shows the jet plunging to the ground in Kazakhstan and then bursting into flames.

38 people were killed.

We know around the same time the Azerbaijan Airlines jet was scheduled to land in southern Russia,

there was, in fact, a Ukrainian drone strike in that area.
