elliott clemence, thanks again.: we are live from the lockheed martin fighter demonstration center in arlington, virginia. steve o'bryan is there as well. he's vice president of the company. steve o'bryan we just heard little bit about the helmet and the technology that's being used. according to a report from the pentagon recently, there has been problems with this technology from radars that don't work to blurry vision from the aircraft sophisticated helmet to inability to fly through crowds. the report includes pilot comment paints a picture of the jet nowhere near ready for real life operation. guest: with the f-35 program there's no denying it's a development program. our job is to find problems as early as possible and fix them. that's what we're doing. if you look at the secretary of defense, his testimony in front of congress this year, he said the program is on track. as we work through these problems, we're continuing to fly the airplane. you can see that confidence coming through on the services and their

elliott clemence, thank you.e'll go back later and talk about the different aspects of the technology that goes into the f-35 but back to steve o'bryan, our guest there at the fire demonstration center. the gao report that we touched on earlier talked about the different challenges what go into the technology for the f-35 and the gao's report said one of the biggest headaches is the lagging effort to write the complex software that is needed for the f-35. can you respond to that. >> well, certainly we have challenges out there today. software is a key challenge. this airplane carries 8.6 million lines of code. just to give you an idea of that capability versus prior generation. prior generations have only about one million lines of code. we have about 86% of that code flying today. we've coded over 95%. but the key challenge is integration of it and the flight test. we've done a number of things to derisk or enable that to arrive on time. so we added about 200 software engineers to the program. we added over $100

joining us is elliott clemence. thank you for joining us.>> happy to be here. host: i see a lot of touch screens instead of switches and dials. why is that? guest: having a touch screen reduces workload for the pilot. back in the old days, there is around 150-plus knobs and that keeps the pilot very busy. screen,r as the touch how much work load is reduced? guest: with the touch screen, your workload is greatly reduced. you can focus on the tactical situation.you can have enhanced situational awareness which affects your survivability. to put that in a different perspective, if the pilot is not as busy with knobs and switches and trying to control precisely where his radar is looking, and he can pay more attention to the big picture and be more lethal as a tactical pilot. host: some of the controls that you do -- this tells you your fuel. if you were to push this, it tells you your weapons capability. this is the overall function of the plane. walk us through some of these other things. guest: this is our tactical situation display. this is our primary display
