It's actually been built by Poma, the French ski lift, cable car builders. To which I have entrusted my life to countless times. Pity the design was done by somebody else.
It's just a big lift really, they often get stuck. The one on the side of the Spinnaker Tower in Portsmouth has never worked. I've seen The Towering Inferno, Titanic and The Poseidon Adventure etc. Things constructed by man often have inbuilt flaws that are not noticed until it's too late.
Great...
