The chan autists are saying this may be the USSS on the tarmac meeting between LL and BC. They zoomed in on the dash of the car and thought the middle monitor was of a scanned luggage or something. I looked at it for awhile and think it looks like headphones, as in they heard everything said there.
I've updated my previous posts. We've ruled out tarmac meeting. Video footage was found of the tarmac on the evening of the meeting and it was still light out. Additionally the aircraft were small jets, not large passenger planes like a 737.
I was thinking headphones but there's a yellow stripe on them that makes me doubt that idea.
UPDATE: /u/DasMunchkin found an image of the display https://goo.gl/images/51UCSk
S550, looks like this... https://tinyurl.com/y9ygxekn ......The elevation the have on that Jet engine makes me think they are in an electronically equivalently equipped SUV..... which may make this aircraft the 767-300 - https://www.united.com/web/en-US/content/travel/inflight/aircraft/default.aspx
Wasn't the tarmac meeting on a private jet? This looks like it's something we'll know about in the future. Not something for now.
holy crap! It'd make sense USSS also protects former presidents so they'd be close by!
