A couple of years ago I'd seen an episode (don't know if it was this TV show) on Discovery or NGC where they showed a very short black/white video.
This real captured video showed a (I believe) 747 pitching up with 90 - 180 degrees because of a failed system.
It could be the autopilot or the system that let the plane quickly climb or desent when another plane is close.
Finally the pilots got back the controls on time and the plane didn't crash.
I'm looking for this episode / video for over years, but I can't find it.

Is there anyone who saw this episode too or know the incident?
I believe it was a Japanees airliner, but I'm not sure.
I hope someone can help me.
