Torres tells Kim that, with the primary buffer offline, Voyager would need to descend to an altitude of 10 km in order to transport their crewmen back aboard. At that height, she warns that Voyager will be detectable by 20th century surveillance. Yet when Voyager descends to beam up Janeway and Chakotay, it gets much, much lower, less than a single kilometer from the ground, close enough to be visible to the naked eye rather than just detectable by surveillance satellites.

The news report shows Voyager flying by the city an hour ago, but it has only been several minutes since the captain and Chakotay were beamed back to Voyager and saw the news report.

When Captain Braxton originally writes the letter "A" on the wall, the letter is written differently when he writes the letters B and C.

During the opening scenes, Janeway is seen holding a tennis ball, from some angles both hands are on the arms of her chair and ball is not in sight.

B'Elanna gives acting captain Harry Kim an emergency transporter range of "probably less than ten kilometers". This corresponds with Voyager's altitude as shown after they beam out Janeway and Chakotay from the Chronowerx office, but the flyby footage shown later on the TV news shows Voyager at a much lower altitude of around 300 to 600 meters. Note the power lines in the foreground.

Shortly after arriving above earth. Paris points out that there are "surveillance satellites here." Janeway orders him to maintain a high orbit. Later the astronomer points out that she has detected something at 40,000 km. But at 40,000 km. they would be at or below most geosynchronous satellites. Many surveillance satellites are in synchronous orbits. So whatever steps Paris took, they were inadequate.

Rain Robinson reports that the gamma source her instruments detected was "in orbit" and "right above us". Strictly speaking, both can't be true at the same time, or at least not for very long, as all geostationary orbits are over the equator and no orbit above Los Angeles can be geostationary. While Voyager could have chosen a non-geostationary orbit, this would be highly inconvenient and also unnecessary since transporter range is usually quoted at 40,000 km in the Star Trek Universe. Also, Rain's display shows an orbit above the equator.

Starling copying Voyager's database somehow removes the files from Voyager's systems. That is not how computer memory works. The files would only be removed from Voyager's systems if Starling intentionally deleted them after transferring, which he did not have opportunity or motivation to do. Therefore there should have been two Doctors, one still aboard Voyager and another in Starling's possession.

[13:38]Neelix describes the television program as a soap opera. He could not have known this terminology because it's a colloquialism. Soap operas are never referred to as such on the air or in the guide synopsis. When discussed in the media, or when previews of upcoming episodes, they are referred to as an operatic drama, much the same way that "porno" is a colloquialism for "adult film".

In the teaser, we see a young Henry Starling in the mountains in 1967, with a fresh tattoo on his forearm. When we see him in 1996, his tattoo is just as fresh. Tattoos fade over time, and after 29 years, Starling's tattoo would not look brand-new in 1996. However, tattoos can be retouched to restore the fading, and fading can also be prevented from fading in the first place by keeping them out of the sun or covering them with sunscreen. There is a FAQ written by Dr. Kai Kristensen who dedicates an entire section to the restoration and/or preserving of tattoos.

Other than a haircut and shaving his facial hair, Henry Starling does not visibly age between 1967 and 1996.

Chakotay and Janeway conclude that the computer boom of the late 20th century should never have happened because the company driving it, led by Starling, was using technology pilfered from the 29th century. But following Star Trek's typical interpretation of time travel, all this didn't happen originally in the time line Voyager's crew lived in. It only happened after Captain Braxton went back in time to the 1960s, which effectively wiped out the time line, to repeat starting in the 1960s, with unknown effects down the line. This ability to change the present by contaminating the past (rather than an interpretation of time travel where the accident of returning to the 1960s was originally built into the time line and thus pre-ordained) is why time travel is taken so seriously in Star Trek.

In a previous episode, the Doctor made Nelix into a Ferengi in a matter of minutes. there is no reason for Tuvok to have to hide his ears when it has long been established the Doctor could make them look human in minutes and return them to Vulcan ears upon his return to the ship.

When Voyager receives the SETI greeting sent by Rain, the greeting, which has been recorded in numerous languages one after the other, is heard in its original form. However, the crew's universal translators should have translated everything into English.

Voyager's transporters are down, but the shuttles have transporters. This was not even mentioned.

Once Voyager came within reach and beamed up Janeway and Chakotay from the room where Starling was holding them at gunpoint, Janeway then tried to beam up the time ship held by Starling. Starling immediately went to his computer and prevented that from happening, and then also accessed Voyager's computer via the transporter link while Janeway and crew seemed unable to stop him from downloading valuable Voyager information from the future. They could have stopped him by transporting him to the ship and placing him in the brig until they successfully transported the time ship and recovered the downloaded Voyager data.

It would have been nearly impossible for even a genius of the 1940s to decipher the nature (let alone operational function) of an Integrated circuit of the 1990s. Similarly, a man from the 1960s (such as Starling) would have been hopeless to comprehend the operation of technologies from 800 years in the future, let alone duplicate forerunners to them.

It is mentioned a couple of times that Starling downloaded 20% of Voyager's data. To download data, in this century as well as the 24th century, means to make a copy of the data from one computer device to another. No one says anything about the data being deleted, but that is what happens.

Janeway says she has no idea what her ancestors were doing in the 1990s, yet we later learn in 11:59 (1999) that she is intimately familiar with the tale of one ancestor in 1999.

There are roughly 140-150 crew members aboard Voyager, only a relatively small number of which are non-human. and yet Captain Janeway selects Tuvok, a Vulcan, as part of an away mission to 20th century Earth. There are plenty of capable crewmen who could have gone who'd have blended in easier.

Neelix is astounded and impressed by the technology and content of television. But he had his own news program which was broadcast on the video screens in Investigations (1996).

While infiltrating Starling's office, Janeway is surprised that the information on his computer reveals that he used the technology from the time ship to build his computer empire. She and Chakotay already found plentiful evidence of future technology in use in his office. Her shocked reaction at that point makes no sense.
