if someone who's a bad actor wishes to shut it down, do they have the opportunity to do so? >> i think that's up to the faa. i see no reason at all why the system which we use couldn't be hard wired so it could not be shut down from the cockpit if in fact thats with a the problem in 370. >> is there any opposition to the programming methodology that you're describing from the pilots? i ask that question because i previously advocated the realtime transmission of cockpit data. i know that raises privacy concerns. they would have no issue with what you're describing? >> i have never heard that the pilots unit had -- pilots union had any problem at all with what i'm describing. i think it's a tremendous enhancement to what we all want to have in a post 2001 world. it just seems so obvious, and since the technology is there, let's use it. >> final question if i might.
