dr. dillingham:. the biggest issue, we are concerned about technology touching each other.bviously there's a great concern when you think about the avionics of an airframe or the communications of an airplane being able to touch the same wi-fi or entertainment systems that the in-flight passengers use. as dr. dillingham: said, while they may be protected with firewalls or devices, those are regularly defeated by bad guys. we have to get better about thinking about building security into these controls at the beginning, at the design phase. i posit that building security into the design of an aircraft is just as important as the leading safety and efficiency features into the aircraft. the world has changed. as things are more and more ip-enabled, we have to think about this from a security perspective as much as a safety perspective. emily: planes that could be affected, boeing 787 dreamliner, airbus a350 and a 380. what percentage of commercial aircraft are we talking about? planes were than 20 years old? dr. dillingham: we do not have account. i would not say that most pl

dr. gerald dillingham, who wrote this report, thank you both dr. dillingham who wrote this report.hank you both. ♪ emily: i'm emily chang and this is bloomberg west. live streaming services from meerkat have been one of the hottest things in tech this year, but just as quickly as they rose in popularity, one seems to be falling out of favor. meerkat has already fallen out of the top 1500 top downloads at the apple store. has meerkat had its 15 seconds of fame already? here to discuss with me, sarah frier. when meerkat cana, i got a pic that opened that said "emily plus meerkat equals boom." is it over? sara: incredibly buzzy, right? just between how much we heard between sxsw and now is pretty stark. that was just a few weeks ago. south by was in march. it is too soon to say it is dead. in fact, it is so tiny that it was barely significant enough in the beginning to warrant all of that buzz. a chart we posted yesterday on bloomberg shows that less than 1% of iphone users are on either meerkat or periscope. it's very early days for these companies. emily: you would say periscope is

dr. gerald dillingham.k weatherford, the former undersecretary for the department of online security. dr. dillingham: i think it is important to understand that we are talking about the potential for this kind of intrusion to occur, rather than saying that this is an imminent threat because faa is in fact taking precautions. we are talking about the future as more and -- aircraft become more internet dependent. emily: how exactly does it work? if the plane is on cabin wi-fi the passenger wi-fi is connected to the cockpit system, back that is where you see the vulnerability? dr. dillingham: as we described in the report, the example we gave is, in the cabin, passengers have broadband available to them. they can upload a program onto their computer. if that program has malicious software in it, and again this is important, if in fact the ip connection on the airports is is able to connect with the cabin and avionics, then you have the possibility. right now what happens is there are firewalls that prevent tha
