Thank you, Mr. Chair.
Mr. Ross, I appreciate that answer. Following up on the supply chain, it perhaps was the colonel who said there were all kinds of stuff in various public reports. Certainly I don't have any way to assess whether or not it is accurate, but I'm hoping you could help me.
Around the operation and maintenance cost we have seen numbers vary rather wildly as to what over the life cycle of this particular aircraft, the F-35, the maintenance cost would be. Can you perhaps share with us some research you have or some work you have done and clarify what is the range of what would be the appropriate operation and maintenance cost for the life cycle of this plane, and how you arrived at those numbers?
