Cool, but Boeing is doing it first with the 777X.
Let's hope, it doesn't fall off...
Cool, but then you'd be forced to fly on a Boeing.
Is that the plane that is already 7 years late due to certification issues?
Neat! https://en.wikipedia.org/wiki/Boeing_777X#Wing
Foldable wings have been on aircraft carriers for a while as well.
Let's hope, it doesn't fall off...
