Men in pedal-powered sub channel-crossing bid

Two men are to attempt to pedal a submarine across the English Channel.

French engineers Antoine Delafargue, 33, and Michael de Lagarde, 36, plan to travel 135 nautical miles (250km) from Plymouth to St Malo.

The pair, who have designed and built the vessel themselves said they expected the trip to take seven days.
