So the production of DS9 was underwater how? What did they have that hard a time constraint.
Just by virtue of how punishing it is to make 26 episodes in a year, TV is nothing but hard time constraints. You're always racing to stay up with the production calendar even when things are going well, and then there's moments where you fall further behind when certain scripts prove particularly difficult to pull together. I've never worked on a show that had more than a 22 episode season and the entire crew is pretty much the walking dead by episode 17, I can't imagine having to do a 26 episode order.
I'm eternally fascinated by just how open and uncensored the DS9 producers are when describing the behind-the-scenes of how the episodes came together and their feelings about the show. IIRC, for this batch they talk about how they had to put extra hands on "Prodigal Daughter" because the script was such a mess and taking forever to wrangle into something shootable, the rest of the staff was working on "Chimera" or "The Emperor's New Cloak", so they had to pull in a freelancer for "Field Of Fire" to even have anything to shoot.
