Thank you, Mr. Chair.
Thank you, gentlemen, for coming.
Colonel Burt, I want to pick up on the simulation thing. Of course, we'd expect any company to have a simulation that shows that their equipment is the best. My question to you is, with regard to the classification level of the capabilities of the F-35, when people are making comparisons with other airplanes than the F-35, how would they know, given the classification level, what they're comparing it to?
