"All the lads said, 'What a guy'"

David Hart, 23, took out life insurance before he went to Afghanistan.
And he wrote a letter saying a chunk of the £250,000 policy proceeds should pay for his pals and their girlfriends to go on a party trip in his memory if he died.
Now 32 friends are jetting to the US – a year after David died in the Helmand danger spot of Sangin.
