They Sat in the Plane at the Gate for Seven Hours...

[Alex]

I can understand systemically how this happens (and much of it is the result of the tight security requirements around an airport).

But I am of the opinion that every airport should be required to build, out near some secondary runway a functional building containing comfortable seating, TVs, minimal food, and restrooms where the occupants of a plane can be offloaded, wait, and reboard when needed without breaching security concerns or requiring use of already booked gates.
