I assume alot of the money goes to make sure the parts are built in European country's that have high quality standards due to strict laws etc..

Some country's in Europe are very very relaxed about quality control and you would not want those country's making parts for Boeing or Airbus.

America has strict quality controls which reflect the quality of the aircraft that is being produced out there and i could never see Boeing sourcing parts from country's with relaxed quality controls as they would have to double check every part.

I dont know if Boeing source parts from other country's btw but if they did i would assume they use country's that have laws in place that guaranty quality.

Also does anyone know how much money the American government have given to Boeing in the past ??
