Could it be a early 747 used for testing on behalf of the certification?? If you look at the top of the tail, there is a sensor (I guess) hanging wired to the tail, probably for registration, so I guess this is test flight...

>>>Can anyone tell me about this incident? Does anyone know the story behind it or anything?
The fact that there is a piece of instrumentation trailing off the end of the vertical stabilizer tells me that this was still Boeing's aircraft when the footage was shot, and as such, was probably a "Vmu" test where they -intentionally- drag the tail to see at what speed the aircraft will fly itself off. The aircraft in question was not yet in passenger service.

Definitely a certification test. They attached a huge piece of wood to the aircraft and deliberately dragged the tail to determine Vmu as someone already mentioned. The 777 had a similar test when it was being certified.
