Backchat hasn't got the hang of all this online business yet. A recent innocent web search to check the spelling of the name of one of the famous TV cooks The Two Fat Ladies led Backchat to more porn sites than you shake a very big stick at (no sexual imagery intended).

So you can imagine the reluctance he showed to log on to the website for fear of what he might find.

But the site is true to the email Backchat received alerting him to it. It allows you to enter the flight you are about to take and then calculates the risk of your plane crashing.

Apparently, this is all based on information gathered for insurers.
