Doug and Tony are transported to the Japanese Consulate in Pearl Harbor on 06 December 1941, the day before the massive Japanese attack. They are surprised by a trio of Japanese that are destroying documents and they tell that they are tourists that had got lost. Tony recalls that this was the last day he saw his father Lt. Commander Tony Newman Sr. that was considered missing in the American base after the bombing. Tony decides to warn his father about the near attack but he does not succeed. Meanwhile the Japanese agents are hunting the scientist to know how far they know about their plans.
Despite the flaws and inconsistencies, "The Day the Sky Fell In" is an engaging episode of this fantastic series. The paradox of Tony meeting Tony is strange, but everything is possible in a sci-fi with the theme of time travel. However, in "Rendezvous with Yesterday" Tony tells that he was born in 1938; therefore he would be only three years old in the attack of Pearl Harbor and the boy is older than that. My vote is eight.
Title (Brazil): "O Túnel do Tempo" ("The Time Tunnel")
