Mr Musk, of course the tracks pushing the main core out of the plane,

they need to have a separate battery.

 

 

Overall, I think the length may be similar to a large passenger plane,

150 meters or more...

 

But the difference is in the volume, storage capacity and how powerful the engines will be.

 

Costly, but will be worth it as it is electric.

 

Safe (three sets of engines), and... comfortable (compartments).

 

I ponder, what if most of the shell was made of plastic? Be it fortified to an extent.

 

Far less damage upon impact, protection against lightning, light-weight...

 

Provided it works with metal covering and the air resistance does not equal out to

instability... (wobbling)

 

Maybe only the certain parts of it... Like the main cylinder that is enwraps the main core.
