Surely there is a whole lot of people who know much more... flight attendants, pilots, co-pilots, other passengers, airport employees etc. This idea of meeting on the ‘third plane’ is certainly interesting..... what, a vacant plane just happens to be handy for a meeting and the much surprised Lynch leaves her plane when Bill arrives and they meet on it? That boggles the mind but let’s assume that Bill meets her on her plane. Was Lynch just travelling with her husband? Was he at the meeting? What about other passengers.... were they all party to the discussion or were they booted off the plane so that Lynch and Bubba could have a private confab? Somebody has details to this....
That’s why they met on a third plane, whose engines were cranking the A/C (108 in Phoenix that day) and the fuselage anti-espionaged and no crew.
Bill met her on the AG’s private jet, there was no third jet. Bill flew in to “surprise” the AG and talk about Golf and Grandchildren. ;)
