I often wondered why Riker didn't separate the ship in "Final Mission". He acted as if the ship couldn't be in two places at once.
Let's see: Picard's shuttle is missing and there's a highly radioactive barge threatening a world. What does Riker do? Split the ship? No, unthinkable. He proceeds to focus on the barge, towing it through a solar system and asteroid belt, coming within mere seconds of exposing over 1000 people to lethal levels of radiation instead of separating, sending all non-essential personnel and civilians into the saucer to scan for Picard while the stardrive tows the barge (as it had everything they needed for that mission).
That kind of boneheaded stupidity seems like court-martial material. If his timing was off by a few seconds, the entire ship would've been dead or dying from radiation exposure with Data as the lone survivor to testify to Riker's epic moment of stupidity.
