The B-17F
Lucky Lass, part of the
United States Army Air Forces (USAAF)
99th Bombardment Group (Heavy) (the "Diamondbacks") from the
12th Air Force is stationed at Navrin,
Algeria in 1943. The opening reveals air crews are expected to complete 25 combat missions before rotation home, but the odds of surviving 25 missions are 2 in 10. During a raid on
Gerbini,
Italy, with her
Irish-American crew, the
Lucky Lass is heavily damaged and the
pilot "Pops" (Jamie Martz), and both waist gunners, Jake (Anthony Ocasio) and Joe (Steve Holm) are killed. Wally (
Donnie Jeffcoat) becomes the Lass'
aircraft commander,
Co-pilot Michael Schmidt (
Bug Hall) reports to Wally, and two new waist gunners, Tom (
Jeremy Ray Valdez) and Oliver (Tony Elias), are assigned. The replacements are introduced to the
alcohol still that
flight engineer Burt (
Chris Owen) has jury-rigged, explaining the Army adds
ethanol to boost the octane rating of
aviation fuel, so they are cooking the fuel to distill out the alcohol. When maintenance chief Sergeant Caparelli (Howard Gibson) reports their aircraft fit to fly, the crew throws a party/
wake to celebrate their return to flight status and mourn their losses. Michael appears standoffish, refusing to drink or eat the local cuisine, and Wally takes him aside to advise him to try harder to fit in. During a "
milk run" an already hungover Wally succumbs to
ptomaine poisoning. Michael takes over and loses sight of the rest of the squadron in the clouds, going off course over heavy
flak defences. Michael returns the crew safely and tells Wally he's going to apply for a transfer. Wally convinces him he can win the crew's confidence, and on the next mission lets Michael take the pilot's seat. Shortly after takeoff, the engines begin losing power and the Lass is forced to abort another milk run to Messina. The crew blames Michael for costing them credit for two easy missions, and when the still is destroyed in a fiery explosion, Michael is branded a
jinx. However, the squadron returns heavily shot up and Wally assures Michael that aborting the mission had perhaps saved their lives.
Lucky Lass is grounded and some of crew reassigned for the next mission. Charlie (Manu Intiraymi), Eddie (Joseph Williamson) and Michael are not assigned. Michael feels guilty but the crew feels his presence will encourage Caparelli to fix the plane properly. Caparelli is loath to order his men to work in intense daytime heat and reports to Michael they can't find mechanical problems. Michael dresses Caparelli down and orders him to inspect the Lass again, in particular the
oil pumps. Caparelli reluctantly obeys and discovers the oil lines fouled with sand. Eddie also pleads with Michael to intervene with Colonel Shay (
John Laughlin) after Charlie was caught stealing liquor from the
officers' club by the
quartermaster, Monroe (Matt Biedel), to make good a promise to Al (Tim Hade) to celebratie his safe return. At his summary
court-martial Michael arrives just as the colonel asks Charlie if there are any mitigating factors. Michael explains the Lass' mechanical problems and claims he ordered Charlie to get alcohol to use as a solvent to clean the oil lines. He accepts blame for not being explicit enough in his order to Charlie. The charges are dismissed, the colonel dresses him down and tells Monroe not to waste his time with non-operational matters. The colonel asks Charlie why he only grabbed
Scotch whiskey, to be told the Lass is an Irish bomber with discriminating taste. The crew celebrates Charlie's exoneration and declare Michael an honorary Irishman, christening him, "O'Schmidt". The
Lass flies again on a mission to Rome. Burt is blinded by shrapnel on the bomb run but manage to release their bombs over the target. Making a turn for home, a B-17 flying above them is hit and despite evasive action, the doomed bomber's wing clips the Lass' right
horizontal stabilizer, causing them to go into an uncontrolled climb until they
stall and then
spin. The plane loses altitude rapidly as Michael and Wally struggle to regain control. They pull up very low over Rome under heavy ground fire and Wally is killed by flak that destroys one of their engines. Tom is killed when he checks on a wounded Oliver in the waist. Michael asks Archie (Sean McGowan) to come to the cockpit to help him fly, since the
navigator was once in flight school. The
Lucky Lass makes a run for a British airbase at
Malta. Michael asks Al in the
ball turret about their situation and is told despite the knocked-out engines and other damage, the B-17 is flying well. The damaged port landing gear falls away as it's being lowered, and Michael orders everyone to bail out, not realizing Archie is wounded. He leaves the cockpit with Archie at the controls to help the crew bail out. Archie opens the bomb bay doors and makes his way back to Michael as the last of the crew exits the plane. Michael is horrified to see Archie covered in blood and in excruciating pain and noticies Archie's parachute has been destroyed. Michael says they can land the aircraft on the water or both jump together using his parachute. Archie nods, but he then tells Michael to "take care of the boys" and pushes Michael out. Archie takes control of the B-17 and climbs until the airplane disintegrates. At Narvin, a new replacement checks in with Michael, now the flight commander of a new bomber. ==Cast==
