Hmm. I thought so. If I was an enterprising young engineering cadet,
I would weld shut the front doors of the theatre and redirect the hydroponics reserve cistern into the lower three or four feet of the old lecture theatre for some epic naval scenery. It would be easy to cut a hatchway through to the elevated walkway in hydroponics next door. In fact… Cunning. It is already on the plans to extend the walkway when it gets repurposed.
Ha! Very enterprising!
