Towards this end, the British have organized fire prevention committees made up of the most representative engineers to investigate and make recommendations of practical measures to reduce the danger on standard power plant installations and fuel systems. It is desired to evolve a machine as nearly as possible resistant to dangers of fire, whether in the air, on crashing, or running on the ground. 

PETRO FLEX.
  One practical result so far that helps is a hose connection. Mr. Blaisdell has developed a gas hose called petro flex which seems to stand all tests that it has been put to. The fact that rubber joints in gasoline lines have been a constant hazard in existing fuel systems has lead the Air Ministry to evolve an all-metal coupling, thus making the complete circuit entirely metal.
