The Lighter-Than-Air Man - S5-E8
Continuity mistake: After Gage opens the baby layette wrapping, he and DeSoto leave the kitchen to answer a phone call, When dispatch calls on Engine 51, the rest of the guys start to pile out of the kitchen, but in the next overhead shot the guys are actually exiting the doorway that leads to the locker room, not the kitchen. The interior of Station 51's setup when facing it is, to the right are Captain Stanley's office and the kitchen, and on the opposite side, to the left, are the sleeping quarters and locker room.
