Airbus is talking about fairness in the procurement process, and how the sole sourcing is undemocratic. Nice sentiment, but it's not going to change any minds.
The fact is, the Airbus A-400 has yet to be built. No Air Force in the world has them in their fleet.
Canada is buying 16 C-130J Hercules, because they are reliable, available, and serving in dozens of militaries all over the world.
Advice to Airbus. Forget what's fair, and open and transparent.
You want Canada to buy your airplane? Then give us 25 A-400s for the price of 16 hercs, and the first 8 off the assembly line.
Anything less and your chances are less than zero.
