Flight of the Phoenix

S2 E9: Commander Adama (Edward James Olmos) is keenly aware that morale is at a low point. Chief Tyrol (Aaron Douglas), still haunted by his memories of the first Cylon Sharon, is in a bleak mood. He verbally spars with Capt. Lee Adama (Jamie Bamber) and gets into a drunken punch-up with Helo (Tahmoh Penikett), who remains romantically committed to the current avatar of Sharon (Grace Park). After sending one more dilapidated Viper to the scrap heap, Tyrol vents his frustration by attempting to build a new plane from salvaged parts. His seemingly impossible mission generates cynicism at first, then growing respect and eventually a full team effort that pulls in even the skeptical Col. Tigh (Michael Hogan). Meanwhile, a Cylon virus penetrates the Galactica’s computers.
