I thought it was kind of funny a number of years back when the US goverment was trying to sue Lucas for the problematic electrical parts that had been put into a number of the US military planes. All they had to do was ask anyone who has ever driven a british motorcycle or car just how great Lucas was before they put it into a plane.. And yes it is proven.. smoke does make things work.. just watch a corvette go up... it's not going to work again...
