 In the next 18 months UK balloonist Rob Franklin will take off with the aim of setting a new British altitude record for a 77,000ft3 balloon by reaching a height of 40,000 feet (12200 metres),
almost one-and-a-half times the height of Mount Everest, and greater than the height reached by most airliners. Breaking the record will mean reaching a height where the temperature is between minus 60 and minus 70°C, and there is not enough oxygen to support life.

The CAA has already given permission for the record attempt, and ongoing support is being provided by many companies and also by the RAF.
To reach 40,000ft breathing equipment, similar to that used by fighter pilots, and specialist insulated clothing are essential. To reduce weight, vital in attempting to reach such a height with a small balloon, Rob will be suspended below the balloon envelope in carbon-fibre frame rather than using a conventional basket or gondola.
This project it totally reliant on the support, services and equipment provided by its sponsors. Several companies have already committed themselves.

Latest developments:
January 2005 >> The new custom-built balloon envelope, made from high temperature fabric, is nearing completion. Weather permitting, it will be inflated for the first time very soon....
February 2005 >> The balloon envelope has been built and test flown, it will be delivered shortly. In the meantime work continues on the carbon composite structure that will hold rob and the fuel tanks.
