Professor Reuben H Simoyi
And this might sound a stupid question, is there steps we can take to prevent it from happening? Was there a human error somewhere? For with the explanation you have given out, I am simply scared to sit in a Heli. By the way thank you for throwing a light on it for it simply baffled me when I read it.

As it was on the ground, the rotors generated a specific vibrational frequency that synchronized with the general frequency of vibration of the whole chopper. Same thing would happen if an army tries to march in formation over a bridge. You can easily bring the bridge down by generating this unique frequency that is cooperative which keeps getting enhanced. We use that in chemical dynamics all the time: a specific unique frequency can generate a reaction (destruction of the chopper), while several other frequencies are incommensurate and lead to nothing other than the noise the chopper makes. If the chopper was not sitting on the ground, it would not have disintegrated because it would wobble and not give any series of frequencies any cooperativity.
