Just thinking, additionally to my cylindrical passenger area (to be detached within

the shell of the airplane in case of emergency),

two rockets can be attached at the torso of the plane,

to be activated during that emergency.

its purpose, to move the plane shooting straight up.

against the trajectory of the jet engines (which should now be failing in that emergency)

and this is to better provide the angle for the inner passenger cylinder to eject,

relying more on gravity, instead a 'push' by the gears. Though that is also possible.

Just an idea. Rockets can be powerful, chemical based. So, would be instant.

Now that rocket, can be embedded to the side of the shell, inside it,

so most of the rocket is hidden inside the shell. Meaning,

it won't get in the way of the aerodynamics.

Only the rocket engines output portions would be exposed from the shell.

So it would look only protruding.

But since, there is the passenger cylinder inside the shell already,

to make way for it, could be tricky, or another location can be used.

Outside the shell, not in the way of the passenger cylinder but attached, to be covered
the contours to blend in with the shell, but really allocated somewhere between the
wing and the shell perhaps.

 

Then now ejection need not be in segments, but whole of the cylinder,
and assisted by gravity. Merely need to detach from the shell from within.
