"The world's longest aircraft dubbed the 'Flying Bum' was seriously damaged on Saturday after it slipped its moorings and crashed into a field....
'The aircraft has a safety system which operates automatically in circumstances of the aircraft breaking free of its mast, and is designed to rip open the hull and deflate the aircraft.'"

Actually helium is made pretty continuously by a number of radioactive sources, no fusion required. Alpha emitters emit alpha radiation particles which are the same as a helium nucleus, which will quickly find some electrons and form helium. The problem is collecting them in any quantity.
This is where the helium in underground wells comes from, alpha decay from uranium in the surrounding rocks, which accumulates in underground natural gas pockets.
