Goofs

When the plane is landing the wording Lear Jet can be seen on the blue stripe to the left of the door, but in the tight shot when the senator is exiting the wording is no longer there.

The 'hourglass' symbol for the project/complex appears and disappears on the floor behind the main control console, depending on the shot/angle. This occurs throughout the series, likely because of reuse of various film clips.

The yellow cups and saucers in the room that Dr Tony Newman is locked in are the same as those seen in the Time Tunnel control room.

The boiler/furnace room door plate has Authorised Personnel written with the Americanised 'Z' rather than the English 'S'.

The edition of the N.Y. Sentinel newspaper's headline refers to the S.S. Titanic. "SS" is a designation for American merchant vessels. The term "Royal Mail Steamer" is the proper designation for British merchant vessels and Titanic was officially "RMS Titanic."

Ragtime music is repeatedly played on the expensive upper decks of the Titanic. Such music would have been considered far too lowbrow. In fact, music on the Titanic was provided by a classical string ensemble.

At one point, Doug tells Captain Smith that the Titanic only has enough lifeboats "for 750 people"; in reality, the Titanic's 20 lifeboats (16 wooden and 4 "collapsible") had space for a total of 1, 178 people.

Obviously, the estimated 704 to 715 actual Titanic survivors did not represent the total number that could have been saved had each and every lifeboat been filled to capacity. Lack of proper lifeboat drills, poor communication between crew and passengers, hesitation of some passengers to get into a lifeboat early on, and a host of other unfortunate issues contributed to many lifeboats being launched that fateful night with far less people than they could have carried.

When Doug comes on board the Titanic, he exits the boiler room. The room has a sign on the door reading "authorized personnel only". But being a ship from the United Kingdom, it should have been spelled "authorised".

Dr. Phillips warns the Senator that they'll be entering "free fall" in the elevator for 800 floors, but their bodies remain firmly attached to the floor.

Downward shots reveal the many levels in the Time Tunnel complex, with people moving along walkways spanning large open spaces. In at least two shots the second and third levels show the same groups of people and equipment, just slightly shifted, revealing that duplicate footage was matted in.

In the wireless room (at 36:07) when Doug tries to explain to the Captain the ship will sink, a photograph of the Titanic can be seen. This picture was taken by a private photographer and not released until after the sinking.

Shortly after the Captain has released Tony and Doug, the two scientists hurry down a narrow corridor. A boom mike can be seen hovering under a header above a flight of stairs as the two approach them.
