I'm right there with the rest of you who dislike 20th Century time travel episodes. That's the primary reason I rate ST:IV as low as I do (which isn't really that low). Regardless, I love "Tomorrow is Yesterday." Maybe because it's the first time our intrepid crew visits the 20th Century?
Speaking of that opening teaser, I want to know how many people thought they were watching the wrong TV show the first time they saw that episode on broadcast TV. That had to throw some people off. Patience pays off and the end of the teaser does confirm it's Star Trek. This rewatch gave me a chuckle that the US military officer automatically went to "UFO" instead of the more logical conclusion that it could have been a stealth fighter. Apparently, though, this episode predates stealth aircraft like the SR71.
I thought "black star" was a better description for "black hole" since it's really not a hole in space. I seem to recall reading once that "black star" was the original term for "black hole." According to this site:
https://www.space.com/15421-black-holes-facts-formation-discovery-sdcmp.html the term "black hole" was coined in 1967, over a year after this episode was written.
I still can't fully figure out how they would have made this a 2 parter to follow "Naked Time." One or both of those episodes must have been reworked. Oh, I can see how the Enterprise being flung back in time in "Naked Time" could result in traveling to the 20th Century. I just don't see getting from Psi 2000 to Earth.
That black star is a navigation hazard. On a route to Earth. Must be close enough to Earth to get the Enterprise there. I can't believe it wasn't already cataloged. Someone is falling asleep on the job!
Uhura reports static. Our modern HD and digital devices don't have static, do they? They simply go silent or blue screen. Static is analog, right? Definitely a technology development not foreseen in the 60s.
First moon shot on Wednesday. Apollo 11 launched on Wednesday, July 16, 1969. So does this episode take place just before that date?
Nuclear missiles? According to
https://www.militaryfactory.com/aircraft/detail.asp?aircraft_id=113 the fighter, a Lockheed 4-104 could be equipped with nuclear weapons. The fighter had a ceiling of 58,000 feet. In contrast, the ISS orbits at 1,341,120 feet or 254 miles.
That tractor beam could be a powerful weapon if used on fragile objects. Apparently it crushes that fighter rather easily. Obviously unintended. Easy to understand how anyone not familiar with such technology would not believe it was an accident and conclude this was some powerful weapon instead of a tool. I have to wonder how the recorder data survived the destruction of the aircraft. Obviously the Enterprise should have pulled the wreckage inside the ship or else let it go so everything would burn up on the way down. Would have saved a lot of trouble.
Odd how Capt. Christopher goes from sitting in his cockpit to standing in the transporter room. Really unusual that he materializes facing the wall instead of the control panel like everyone else normally does no matter which way they were facing when beamed up.
Yay Kirk with the smirk at Christopher's surprise toward female crewmen. Kirk is quite comfortable working with women under his command. He's just not comfortable with working in close contact situations. That sly horndog. At least he knows his limits and boundaries when he's not split into separate halves.
United Earth Space Probe Agency. UESPA. Different than Starfleet Control (not Command in this episode). Perhaps Earth's military combined into the UESPA?
I see people in the future are just as illiterate when it comes to computer settings as they are today. It's not hard! Settings/System Preferences/Siri/ choose language, choose voice. Surely out of 430 people someone knows how to change the preferences for the computer voice. Speaking of the computer, is it an AI of sorts? It sure sounds like an emotional response when Kirk makes a note to reprogram the personality. Almost like it didn't like that idea. And, yes, the easy sounding voice is unlike the normal computer voice sound. It must be in the settings somewhere.
No civilian styles of clothes available? Christopher was given command gold to wear. Kinda odd to dress a visitor up in the standard uniform when the visitor isn't a member of that organization.
Stardate 3113. 3 years into the 5 year mission? We have been up and down the thousand units so far this season.
Again with the visitors on board ship having free access and no supervision. Christopher wasn't in his quarters and was able to get all the way to the tranporter room unnoticed. 430 people and those corridors are empty? He easily accosts the nonchalant security guard and steals his weapon. Talk about someone not on the ball. Good job there pal. You are now reassigned to waste disposal.
Col. Shaun Geoffrey Christopher. Named after writer John D. F. Black's 3 sons; Shaun, Geoffrey and Christopher.
I liked the conversation between Sulu and Kirk about the antique museum computer pieces. Why, though, is Sulu part of this landing party? Helmsman, botanist and now historian? Well, he did like the antique police revolver from "Shore Leave." But he imagined it with 7 bullets.
200 years is about right to get Kirk back to his own time? That puts Kirk at the end of the 22nd Century. That's a far cry from "Squire of Gothos" where Star Trek is implied to be in the 27th Century (900 years from the Napoleonic Era).
Again, how do these food slots work? They're neat! Want chicken soup? Get chicken soup. Just put in a slot card. Surely that slot card doesn't have every recipe on it, does it? Why not have that in computer memory? Maybe the card was an access card and you can't use the food slot without the key. Why are there food slots in the transporter room? No dining tables, just food slots. Eat standing or on the floor! Is it normal that someone gets suddenly hungry before beaming out or right after beaming aboard?
Slingshot around the sun makes it's return in Star Trek: IV. Slightly different than the Psi 2000 timewarp even though both involved warp and a gravity well. Time and gravity and space must be related or connected. The crew seem quite accepting of the fact they traveled back in time. Like, "of course, we knew this could be a possible side affect of such a slingshot."
