Upgrade or just repairs?
Starbase repair staff enter the Engine Room. One counts the horizontal tubes behind the mesh and begins sucking his teeth.
Repairman: Blimey, would you look at that - the entire engine block - the WHOLE THING has dropped a clear foot! How did you not notice?
Scott: How dare you! Ma poor wee bairns are treated with love and kind-
Repairman: Never mind, Welshie. We'll fix it, BRING IN THE CRANE!!!
