I’ve seen a concept of an airplane that can eject sections of it’s hull, each equipped with a large parachute. This can solve the problem of “how to put parachutes on each passenger including kids, disabled and panicked and teach them how to use it”. Also it doesn’t require the plane to maintain certain height, speed or angle for parachuting.

But of course it will add extra weight to carry, because not only they’ll need to install big parachutes, but also ejection system and something to seal off ejectable sections.
