The VPN requirement recommendation was for air-ground and air-air
communications of devices or systems that have safety importance to
aircraft.
I am not aware of a security or safety reason that would require
VPNing
passenger communications from aircraft. One may debatably want to
do it
for non-security or non-safety reasons such as consistency or
performance (e.g., an ATM study has tentatively concluded that
there are
performance reasons to use VPN).

Clearly those domains cannot interfere with one another, and clearly
there are mobility considerations for all of the domains that relate
to routing and addressing.
Sure - I understand VPNning aircraft stuff (though there's no reason
this can't work with MANET). I don't understand VPNning
passenger stuff.
