I stand somewhat corrected. I'm going to claim that Lost in Space and My Favorite Martian were broadcast during a period when television shows couldn't acknowledge sex. Keep in mind, Laura and Rob Petrie slept in separate beds and they were both humans married to each other. Battlestar Galactica sure had alien prostitutes in the "Guns of Navarone" episode, I think it was called The Gun on Ice Planet Nine or something like that. I don't recall Earth II, and IMDB only finds a movie.
Okay, how about I modify my statement to be, "Every live-action American television show broadcast in color eventually has includes sex with aliens, if aliens are present." That gets rid of the Firefly exception for me as well.
2) While I agree, remember that the crew is mostly cadets and recent graduates. There probably weren't any dedicated soldiers with grenades.
What, the Federation didn't realize they were building a new starship and that she might need a crew? Did the discovery of warp drive destroy all concept of workforce planning? How can you build a ship and not have a crew in training, along with a adequate number of transfers to act as cadre?
Oddly enough, the National Debt increased every year of Clinton's terms of office. Strange that he could manage a "balanced budget" while the National Debt increased, isn't it?
Yeah, it's called interest. The budget is balanced, but the interest on the debt causes the debt to increase.
Life is a whim of several billion cells to be you for a while.
