It's 60 years since the British inventor Christopher Cockerell demonstrated the principles of the hovercraft using a cat food tin and a vacuum cleaner. Great things were promised for this mode of transport, but it never really caught on. Why?
The hovercraft slides down a concrete ramp and into the Solent. Its engines, propellers and fans hum as it crosses from Southsea, in Hampshire, to Ryde, on the Isle of Wight, travelling 4.4 nautical miles in under 10 minutes.
The journey is more than twice as quick as the catamaran from Portsmouth to Ryde and more than four times as quick as the Portsmouth-to-Fishbourne ferry.
For that matter, why haven't hydrofoils caught on?

Yeah yeah I know but there's just so many ways the task is incredibly expensive I couldn't resist the chance to mention the bird kill problem and the difficulty of making turbines that eat large birds and keep running (like jet aircraft engines, well, at least sometimes) and chipper shredder analogies and ...
Its just so roadrunner cartoon, sign up for the ACME air fan and it just works, but really moving enormous amounts of air is just a PITA engineering challenge.
