A Firm Grip on the Cabin Wall

My fingers suddenly twitched with purpose! I blinked at the clear sloped windscreen right before me. Everything around me was locked tightly in neat layers of bright plastic. Curious, I raised my right arm and gave the pale blue brick by my shoulder a solid tap. Click! It held firm, sturdy and real. I flexed both hands, marveling at how smoothly my joints turned, and settled right back into the snug seat, ready for whatever rolls next!
