commercial operations like this, it's fairly routine. you have to scratch your head to think the last time you had a crash landing like that. certainly in the u.s. i think that's right. there is no good reason these days if you're going to film a grocery store 24/7, you probably should have video cameras strategically located at airports to help in understanding what may have happened or more importantly, prevent accidents happening before they end up like this. >> it's interesting. jim tillman, as i walk around the building at work, one camera there is a camera, the lobby there is a camera, why not on runways, jim? >> there is no good reason for not having cameras there. i can't think of one good single reason except we haven't done it. they think they use one video every 50 years so it's not worth the effort.
