Probably the best example you will see of flutter on an aircraft. Ramy's first flight at Airliner Treffen Show nearly ends in disaster when the push rod on the rudder becomes lose and the flutter destroys the lower part of the rudder. Added to that a bad hinge on an aileron results in flutter of the left wing. It all could have gone very badly wrong...

Terrific video.
The only comparable one I can think of is that of a jet in a knife edge pass losing its fin/rudder due to flutter and then the whole fuselage disintegrating.
If you can remember which video it was, please post it here (it was shot by you!)

Really...I don't remember that one, but I do have a very bad memory.
