No chance! Hopefully.
It could ever only work ILS to ILS anyway, there's more to it than just the a/c technology.
And if they're controlled from the ground they'd have to secure the carrier frequencies or one wouldn't even need to get onboard.
There seem to be so many problems, some of them almost certainly irresolvable. I'm in my early 20's and wonder if in 40 years I'll be more worried. Were young engineers worried in the 60's?
