mr. misener's, the application he was talking about earlier. that does require beyond visual line of sight. that is all manner of inspections that i was mentioning as well. bnsf was mentioned earlier being able to check for split rails in advance of trained. other infrastructure, et cetera. and just if you imagine one of the early applications, early adopters of this technology will be agricultural interest, farmers, looking to all manner of inspection of the property. some of these farms are large of course and so could easily be flying over the property but haven't well beyond line of sight. again basically flying a pattern that a computer is controlling. very low altitude. these are the types of operations that we think, some of them are more complex than others but we think there's a way to advance the technology, to test the technology. the more we are flying, taking him to the level of safety to the current aircraft system, airspace system that we have today, the more dated can collect, the more we contest technologies like detect and avo
