Scottish firm engineers superwheels

The process of machining the fastest wheels in automotive history has begun.

The aluminium discs will be fitted to the Bloodhound Supersonic Car, which will endeavour to break the world land speed record (763mph) later this year.

Castle Engineering near Glasgow is leading the industrial consortium that is preparing the wheels.

MD Yan Tiefenbrun told our correspondent Jonathan Amos how the firm became involved in the project.
