Here it is
"air travel is the safest way to travel on a per mile basis -but it is no safer then cars on a per trip basis"
This is stated by many aviation journalists and aviation safety activists.
This maybe true but it is grossly misleading. Most car trips are under a few miles (90% under three miles in England). How can you compare that to an average air trip of several hundred miles. Should you compare a 3 mile trip to the groceries with a 1000 mile flight to another city?
Moreover the risk of accident from car journeys is preportional to miles driven - whilst aviation risk is only perportion to each take off and landings.
Perhaps the most useful statistic is the risk per journey of a given stage lenght where either car and plane can be used. ie say 300-500 journey. This eliminates the 3 mile grocery run which planes are not practical. It also eliminates the long haul flight where cars are practical
