I would like to know if its possible to know how aircraft companies like Boeing or Airbus get financed. There is of course, the cost of an aircraft paid by airlines or leasing companies. There are also shareholders .I also suppose governments in the U.S for Boeing and the E.U also make some kind of subside via tax money. Do some airlines also participate financially to the developemnt of an aircrat. I always hear how the 764 was made specially for CO and DL and how EK always puts pressure on Airbus or boeing to modify an aircraft.
Thus I would like to know what the different sources of income for A and B could be that I have forgotten to mention.
thanks in advance
