"It requires no stretch of the imagination to conclude that the current helmet craze is likely to have been propagated by the Government, possibly with the involvement of the FCC. We hope this report will encourage the paranoid community to develop improved helmet designs to avoid falling prey to these shortcomings."

Re: For some reason

one of these pictures brought to mind the pope, wearing a tin foil hat.
Can someone of an intellectual bent also do me a favour and explain to me why Americans say 'Aluminum' and we Brits say 'Aluminium'? Was the 'i' lost in translation so to speak, or was it deliberately axed?
