When the crew are captured, they are disarmed; however, when they get into a firefight later, Janeway draws her phaser from her holster.
When Voyager is on its landing approach, it is shown descending through a cloudy, turbulent atmosphere. However, once the ship has landed, and for all the subsequent outdoor scenes, the sky is a clear, cloudless blue.
Paris reports that benzene, acetylene and ethylene would have been present in gasoline. There could be small amounts of benzene in gasoline, but acetylene and ethylene have too high a vapor pressure to be in gasoline.
The battery, oil, and gasoline in this truck were exposed to temperatures of approx. -240 c or approximately - 410 f. Even metal is affected by temperature extremes that great. A liquid acid battery of the type used in the 1930's would have frozen and broken the battery (perhaps into separate pieces). And therefore made starting this truck without electricity impossible. Oil and gasoline would have changed states at that temp and probably lost many of their useful properties. Making it highly unlikely that this truck could start (even it had electricity) and idle.
The 1936 model Ford truck found drifting in space for 400 years and beamed into the Voyager cargo bay not only has tires still perfectly inflated with air, but also has enough gas & oil in the engine, as well as a charged battery, so that Lt. Paris is able to start the engine on almost the first try. In the total vacuum of space, air would have almost instantaneously purged itself from primitive 1936 truck tires, as would oil, gas, etc., from the engine. In addition, a 1936 car/truck battery also contains water and is not going to retain water and/or an electrical charge in space for 400 years.
Amelia Earhart's compass would have worked on the planet. All a compass needs to work is a magnetic field.
The trucks AM radio would not pick up a 1930's aircraft sos for 2 reasons. The aircraft would be operating in the lower HF band and the trucks radio receiver in the AM broadcast band. Neither one of the frequency bands would penetrate a class M planets ionosphere. The are ground wave RF.
When under fire, Chakotay and Janeway take cover behind large rocks which move when touched.
As Tuvok and the rest of the rescue party are making their way towards Captain Janeway and the others, a butterfly can be seen flying around the actors.
On Voyager's bridge, Amelia Earhart asks Lt. Paris, "How fast?" Lt. Paris replies "Warp 9.9. In your terms, that's about 4 billion miles per second." Four billion miles per second is 21,505.38 faster than the speed of light. This would have let Voyager travel the 75,000 light years it was sent in about 3.5 years, thus ruining the storyline of being over 70 years from earth and the Federation.
After Janeway tells Chakotay by communicator that her team has been taken hostage, Chakotay dispatches an armed rescue party. But when the captors make peace with Janeway and head out with her to the ship, Janeway and her team never call Chakotay or the ship to tell them the situation has been resolved.
When Amelia Earhart and Nogami (the Japanese guy) are woken from deep freeze, Nogami is confused about the Star Fleet personnel speaking Japanese. Captain Janeway explains that this is due to the "Universal Translator" that all the Star Fleet crew members are carrying. Yet, later on, Nogami and Amelia are able to talk to each other when no "Universal Translator" is present.
Chakotay asserts that Voyager could not be operated by less than 100 people. Yet 70 years earlier, in Star Trek III: The Search for Spock (1984), the Enterprise NCC-1701, a much more primitive Constitution Class Starship which normally housed a crew of 430, was swiftly modified by Scotty to be flown on a rescue mission by a crew of just 5 people. It is highly improbable that the much more modern and sophisticated Voyager (with all its advanced systems and computers - even a Holographic Doctor) would be so much less efficient. Furthermore, later in this series there are a few times when Voyager runs with a small skeleton crew similar to Scotty's.
