So Airbus do get some start-up subsidies from the governments. But all are repaid usually at a higher rate of interest than those loans you could pick up at your average high street bank.
If things do change I get the feeling that Boeing may end up shooting itself in the foot when the enormity of its subsidies are fully visible to all!
Let's just get on with building airplanes......it's been said before there needs to be several good manufacturers competing to drive technology forward, not one that is dominant.
