The Time Tunnel

Dr. Tony Newman prematurely enters the government's Time Tunnel project, and the project head, Doug Phillips, must go back to save him as they both fight for survival on the sinking Titanic.

Doug and Tony land 10 years in the future on the Mars Excursion Module during liftoff. Their extra 335 pounds of weight endanger the mission by putting it over the weight allowance. Everyone believes the time travellers are spies except one man, Harlow. They are forced to land on the moon for a refueling stop, but the ship crashes. One of the other men, Beard, kills Harlow. Beard is a spy. To further confuse matters, ten years in the past at Project TicToc, Beard and another spy, Brandon, are visiting the complex. Brandon sabotages the tunnel and then tries to escape, but Beard shoots his superior to bolster his own cover and his own role remains undiscovered. In the future, Doug and Tony manage to blow up the ""future"" Beard, but the MEM takes off without them. As they are stranded on the moon, their air running out, the Tunnel scoops them up and sends them on their way. (Copyright 2003 Steve Crow)

Dony and Toug arrive in 1910, where a local town is in a panic over the arrival of Halley's Comet. Tony is caught in a cave-in near two hundred miners, while Doug is unable to get help from the superintendent, Henderson, who believes they're all doomed because of the comet. Doug digs out Tony on his own, and tries to convince the local astronomer, Ainsley, who has everyone in a panic. While Tony tries to set up a rescue, the Project team try to send Doug a radioscope through the Tunnel. That plan fails, but Doug makes a primitive radioscope and shows Ainsley the gravitational forces that will cause Halley's Comet to deviate. Ainsley convinces the townspeople they are not doomed, and everyone teams up to rescue the miners. Meanwhile the Tunnel sucks in Halley's Comet and the power flow almost sucks Jerry into the Tunnel before they can cut pull the plug.

Tony and Doug land in the Japanese Consulate in Honolulu on December 6, 1941, and see three men burning files. They talk their way out and Tony goes to find his father, who disappeared during the bombing. Cmdr. Newman is initially skeptical, but Tony convinces him with family knowledge no one else could know. The Japanese agents get wind of Tony and Doug's knowledge, capture the pair, and interrogate them for information. They don't break, and manage to escape. Meanwhile, Cmdr. Newman is at Naval HQ checking out Tony's warning, and the Project staff realize that if the young Tony (who was also present at Pearl Harbor) isn't rescued, then ""their"" Tony will vanish. Tony manages to convince the housekeeper, Mrs. Neal, to flee to the mountains with her child and Tony, and then he goes to rescue his father. They head to Naval HQ but a barrage hits and Cmdr. Newman is killed. An unexploded bomb lands, and the Project staff use the Tunnel to delay it long enough for the travellers to get clea

Tony and Doug land in the War of 1812 in Louisiana, and steal som clothing that happens to have passes from General Jackson. They are captured by the British forces, led by Colonel Southall. In the present, the Project people bring in Southalll's descendent, a British general. His ancestor has a reputation as a butcher by sending his men into the strongest flank of the American forces. In the past, Col. Southall forces Tony to lead one of his men to the enemy lines, get a report, and send up a signal rocket of which flank he should attack. Tony and the scout get captured, escape, and prepare to send the signal. Meanwhile, General Southall insists on returning to the past. He's dying of cancer, and Kirk reluctantly grants the general, an old friend, his last request. The present Southall helps Doug escape and then confronts his ancestor and manages to convince him he is from the future. Doug helps Tony but the signal rocket goes astray and the attacking British are wiped out. General So
