The aviator or team that covers the most distance before plunging into the sea wins.

  This is for serious contenders competing over both days for the £25,000 Jackpot, the International Birdman Trophy and other money prizes, including £25 per whole second for the longest time aloft up to a maximum of £1,000.
• The Condor Class: for modified hang gliders and similar craft.
• The Kingfisher Class: for topical or comic entries, usually fancy dress. This Class offers excellent opportunities for sponsored fund-raising and there are prizes for the most money raised.
