In my RAF days, flying Support Helicopters there was a song:
There's a Wessex on the ground, on the ground
With its rotors going round, going round
It jumps up and down and shakes itself to bits
And gives its passenger the $hits, $hits, $hits.
Based on a true story.
I'm not sure if it was the one that rolled itself over between the hangars at Shawbury late 80s/early 90s?
Every Wessex pilot knew the risks of ground resonance in the old girl but more scary was doing full power pulls with the aircraft chained to the ground - you knew if any one of the chains let go, it was going to be brown underpants time.
