Thunderbirds Logo 'Danger at Ocean Deep'
by Donald Robertson
Thunderbirds Cast

After Lady Penelope launches Ocean Pioneer I, the ship then mysteriously disappears. When International Rescue later experiences mysterious radio blackouts in the same area of the ocean, Brains traces the effect to the explosive reaction caused when Ocean Pioneer’s cargo of liquid alsterene came into contact with OD60, a chemical dumped at sea. Ocean Pioneer II is now about to be launched, also loaded with a cargo of liquid alsterene - and is heading for the same fate as its predecessor...
