What is Abdoul Masmoud Yessoufou trying to do? "Stowaway Boarded US Carrier," From [1] Isle of Wight County Press, with thanks to Twostellas:

Abdoul Masmoud Yessoufou, 37, whose address was given at Portsmouth Magistrates' Court on Wednesday as East Street, Newport, admitted entering a prohibited area at Portsmouth Docks.

The court was told that Yessoufou was found on the USS Harry S. Truman at the weekend after he strolled past guards and hitched a ride out to the carrier on a boat used by sailors on runs ashore.
Yessoufou had previously appeared before Uxbridge Magistrates three times this year for entering restricted zones at Heathrow. He also reached the side of an aircraft at Southampton Airport in January.
