Mechanic Cory races against the clock to turn two short-haul waterbombers into trans-Atlantic aircraft for the epic journey to Turkey. It's up to engineer Adam to get the C-46 crew out of a jam on a remote airstrip in minus 40. And when captain Devan and co-pilot Scott encounter the menace of wind shear at notorious Bear Rock, it's a hair-raising experience that tests their friendship.

A charter flight falls through the cracks after the McBryans attend a wild family wedding, and an irate Joe pulls captain Justin from the Turkey test flights to do the job. Justin's task is to move an impatient Brit, his dog and all his worldly possessions to a remote northern outpost, but the weather isn't cooperating. Meanwhile, Devan ponders a job offer in Africa - leaving girlfriend Jynelle to ponder their future.

A furious Joe fights against a federal suspension that will prevent him from carrying passengers for the first time in 20 years. It's also a setback for Jeremy and the other rampies, which takes a turn for the worse with an unexpected injury. For the Turkey waterbomber team it's finally a go. Arnie, Justin and the crew set off on the first leg of their journey, a risky trip across Canada in the dead of winter, with no de-icing equipment.

The Turkey crew makes the critical jump over the North Atlantic. But en route to Portugal, one crew is forced to turn back. With no power on one engine and no way to maintain altitude, they must get back into Santa Maria, where the airport is on full emergency alert. And Mikey and Scott search for a new rampie, while Jeremy's hopes plummet even further.

Joe gets a lucrative late-season contract to fly mining equipment to an airstrip on a frozen lake, sending C-46 and DC-4 crews on a race against the spring melt. But conflict erupts between Devan and a senior pilot. And when the client reports an on-site incident, Joe goes on the warpath. Though Jeremy has missed a number of flight attendant classes, he's confident he can catch up to fellow rampies Audrey and Wilf. But too much confidence just may be a dangerous thing. And over the North Atlantic, Arnie, Justin and Cory press on to Turkey, even though they have only half of the spare parts in their plane. But there are some serious volcanoes and busy Mediterranean air traffic ahead.

Across the world in spectacular Izmir, after thousands of hours of painstaking preparation and life-risking flying, a terrible accident devastates the Turkey crew - and everyone at Buffalo Airways. In Yellowknife, the spring melt is well underway, and northerners are finding ways to celebrate, from checking out the melting waterfalls to racing jet boats onto the remaining river ice. It's also Wilf's first run as flight attendant on the DC-3 - for which he insists on wearing a shirt and tie to the consternation of the entire company. It's the final push Jeremy needs to move to HQ in Yellowknife. Kelly and Jynelle dig up a house-warming surprise that practically brings tears to the gruff rampie's eyes.

Cargo manager (and unofficial Buffalo den mother) Kelly has problems enough when Jynelle's holiday leaves her shorthanded. But when her engineer husband Juan quits on the spot after a blowout with Joe, Kelly is left in a terrible position. Will Kelly stay - or will she go? Scott also gets bad news: he must stand down from flying so a rival co-pilot can be fast-tracked to captain. Scott pulls out all the stops to secure a new contract flying practically to the North Pole, which will get him back in the pilot's seat. But his rival is also interested in this new dream job - flying the C-46 to Eureka, a tiny research station at the top of the world. And after nine months of brutal work and tough luck, Jeremy sees light at the end of the tunnel. Buffalo needs a new DC-3 co-pilot, and contrary to expectation, he's getting a crack at it. But first, he's got to pass the test of flying with Joe.

After her husband's acrimonious departure from Buffalo, Kelly has a confrontation that decides whether she, too, will quit. Jeremy makes a mistake that could end his Buffalo career. An aviation gas shortage brings a sobering dose of reality to the McBryans. And after a visit from his mom, fate throws Scott an unexpected curve ball.

Meanwhile another Buffalo co-pilot, Andrew, is up for a job with Cathay Pacific Airlines. The last time a pilot left, Joe took it personally.

After taking command of an intense airlift, and dealing with the ugliest Electra load he's ever seen, Scott takes a scary fall on the icy tarmac. City girl Christine moves to Yellowknife to give the unglamorous rampie life a shot, firebrand mechanic Chuck returns to the Buffalo hangar and immediately stirs the pot, while Joe helps out an old friend, "Ice Road Trucker" Alex Debogorski.

A week before Christmas, Buffalo agrees to lend a hand to an RCMP initiative to fly toys to isolated communities in the north. But a series of problems with the Electra leave the company in a jam. An excess of holiday freight overwhelms cargo manager Kelly, and despite a visit from her buddy Arnie Schreder, recovering from his cancer treatment, her stress peaks after a clash with Joe.

Just months from retiring, Electra captain Ray Weber leads his crew on a multi trip mission that requires landing on a rough ice strip on a remote lake. The ice strip landing goes fine, but when the plane takes off from the strip, the right landing gear gets stuck in the wheel well. Ray and his crew try to get the wheel down but to no avail, and are forced to perform an emergency landing that they'll never forget.

When South Korean buyers come to Buffalo to look at a water bomber, the pressure is on mechanic Cory to get the plane ready. But a landing gear emergency puts him and chief pilot Justin in serious danger. Rod and Mikey salivate over a fleet of P3 Orion water bombers up for auction at a California fire fighting conference.

Mikey gets the opportunity of a lifetime when he's invited to host a classroom discussion with Commander Chris Hadfield, calling in from the International Space Station. But reality soon hits, when the first blast of a record-cold winter grounds the DC-4, causing a major backup and grief for new cargo manager Chris Staples. When Mikey dispatches the C-46 to save the mission, it suffers a landing gear collapse on the runway, forcing the entire staff to scramble – with no word on the state of the flight crew.

Buffalo Airways is still reeling from the recent accident – especially mechanic Chuck. Mikey tries to lift spirits by setting up a hockey shootout against a squad of NHL players that the airline is transporting around the north. He drafts a team and Buffalo's best players – including Chuck – test their shots against Ottawa goalie Craig Anderson. Young DC-3 co-pilot David flies farther north than he's ever been, facing a mysterious landing gear problem on approach to a remote Arctic airstrip. When his captain gets flustered, the rookie has to keep his cool.

Joe preps for a race in an antique snowplane – a 1940s ancestor of the snowmobile, powered by an airplane engine and devoid of brakes. No one knows what will happen when he unleashes it on frozen Great Slave Lake. The water bomber crew, led by Justin and Cory, try to move their two fire-fighting planes from Turkey to a maintenance facility in Wales, but get tangled up in red tape, threatening to ruin their chance of meeting up with Iron Maiden front man Bruce Dickinson. Rampie and cocky aspiring pilot Chris Staples pushes his way onto a C-46 flight, where he makes a critical mistake. AJ makes a last-second overshoot.

After a breakdown uses up the last of Joe's spare DC-3 engines, he enlists former Buffalo pilot Devan Brooks to ferry another plane all the way from Quebec. Flying 3,000 kilometres in a DC-3 that's been mothballed for 7 years, Devan faces a critical hydraulic leak at the worst possible moment. As a massive cold snap paralyzes the hangar, a major landing gear problem strikes the nightly passenger flight to Hay River. Captain Justin Simle has to make a snap decision with a full load of passengers on board – including his own newborn son.

Following almost a year of repairs after its crash landing, Buffalo Airways' Electra returns home to take on an urgent mission – returning to the very ice strip that set off the problems last year. It's the ultimate test for the plane and the crew. DC-4 co-pilot Tyler makes a major decision about his future, but now he has to face Joe. A pilot shows up out of the blue – all the way from Australia. Will Dyer has ten times the experience of a normal novice and quickly works to win a seat in a Buffalo cockpit. But the company throws him a curveball that puts his future in doubt.

Joe's stress over the state of his water bombers, currently being stored in Wales, sparks an angry blow up with Cory, pushing Cory and Rod to head to the UK for urgent repairs. A day of culture in London leaves the hosers cold until they hook up with their British host, Iron Maiden's Bruce Dickinson. But at Bruce's Welsh facility they run into snags that threaten the work. David flies with Devan in the C-46, hoping to show how much he's learned. But when David badly botches a takeoff, Devan threatens violence. Instead of flying, hotshot Aussie Will gets stuck working on the ramp in Hay River, pushing him to a harsh ultimatum.

Mikey joins the Canadian Rangers for an extreme outdoor training experience farther north than he's ever been. While he's gone, a military Aurora takes refuge in Buffalo's hangar for important repairs – pushing Buffalo's own mechanics out into the bitter cold. What should be a simple fix turns into a multi-day ordeal and the Air Force has to go head-to-head with Chuck. Joe flies to California to bid on a fleet of firefighting planes that could revolutionize his company. But he discovers he has tougher competition than he ever expected.

It's Joe's 69th birthday and he's never flown a helicopter before. So Mikey plans a special gift of chopper flight lessons, complete with surprise pickup in front of the Buffalo hangar. Mikey jumps in for the ride as Joe struggles with the unfamiliar beast – and both McBryans will learn if they've finally found an aircraft that Joe can't master. Another cold snap has cut off heat and power in a small northern town. AJ and James battle a frozen engine before they can head up with a load of supplies. On the way home, an engine fire forces the crew into an emergency shutdown.

The Electra has become Buffalo's winter workhorse – the one plane they need to keep flying. During a High Arctic delivery mission, a 5,000-pound power unit tips off the forklift and crashes to the ground, smashing the fuselage – and sending Mikey into crisis management mode. With no backup Electras, Joe races to Atlantic Airways in Coventry, England on an urgent mission to scoop one up from other potential buyers while back at Buffalo, Mikey tries to prove he's really management material.

Co-pilot Graeme Ferguson gets the biggest opportunity of his short career when Buffalo needs to train a second Electra crew. But none of Buffalo's piston-pounders have prepared him for a plane this big and this fast. When Graeme fumbles a landing, he has to prove he's ready for his big chance after all. Meanwhile, Chris Staples gets to take the test he's been dreaming about – to qualify as a co-pilot in the C-46. But he'll have to take it with one of the toughest captains on the crew. When the C-46 breaks down in Deline, Adam Smith rushes to the rescue and Chris might finally get his chance to shine.

The Electra is still working around the clock and Buffalo is ready to pick up another, the second of its new British acquisitions. Joe and Mikey head across the Atlantic to fly home their new baby, ending an era of British aviation. Devan preps for fire season with some wild target practice in the DC-4 to see if his aim lives up to his cockiness. When James' son enters the local soapbox derby, James builds a Buffalo-style racer and finds out how his ugly green machine stacks up against the slick and pretty competition.

Mikey and Joe visit the Hamilton air show where Mikey has planned a major surprise for Father's Day. Joe is going to ride along in a CT-114 Tutor Jet with the famous Snowbirds. While Joe prepares for the big event, Mikey decides to conquer his fear of heights. He travels down the highway to Toronto and tries out the CN Tower "Edgewalk." But he's determined to go even higher. After all the bonding he and Joe have done in Hamilton, Mikey takes his first pilot lesson with Joe as the teacher. It turns out there are some heights Mikey still fears. As spring warms up Yellowknife, a longtime member of the Buffalo family announces a surprise departure.

It's been a wild five years for ICE PILOTS NWT. To celebrate the milestone, we pull back the curtain for an inside glimpse into the production of the TV show, and allow the cast of Buffalo characters to reflect on how it's affected their lives, for better or for worse. And we meet the cameramen who navigate prickly personalities and brave minus-forty conditions to capture the footage that has made ICE PILOTS NWT a cult phenomenon.

It’s Buffalo’s busiest winter yet, and they roll out the C-46, TXW, to fly all the freight up the Mackenzie Valley. But when one of TXW’s engines catches fire, Buffalo scrambles to find a backup plane in time for Christmas deliveries. They look to their newly purchased Electra, XFC, to fill the void, but Adam, Chuck, Brian and Mikey discover it has a cracked windshield and cannot be flown safely. Joe, Brian and Cory fly to meet Rod in Red Deer to grab a replacement windshield. When they arrive, Joe first reveals his other plans—he wants the second Electra ZFE dug out of the snowbank where it’s been sitting for months and get it up and running so that it can replace XFC on the Valley run. Rod’s upset that he wasn’t given more notice, and unloads on Mikey about Joe’s reactionary management style. Back in Yellowknife, Buffalo’s newest rampie, Prefkar Mony, is a determined young pilot from India who’s got his eyes on flying Joe’s prize planes. But first he has to adjust to life in the North—and purchasing proper winter gear is the first thing on his list

Chief Pilot AJ Decoste is flying up the Mackenzie Valley with Buffalo’s newest Electra, XFC, for the first time. Mechanic Cory Dodd is along for the ride to do some training as a Flight Engineer. They try to make their deliveries before a storm rolls in but when they land in Norman Wells, they are faced with gale force winds. When their takeoff is delayed by two incoming planes, AJ is forced to shut down and wait out the storm in Norman Wells. Later, on their approach to Tulita, they face even stronger winds gusting over 40 knots. Over in Hay River, things go from bad to worse when a warm weather system brings the threat of a rare ice storm. Two daily skeds arrive from Yellowknife and the rampies have to batten down the DC-3s in preparation for a long, rough night—the worst storm in fifty years. And the newest rampie, CJ Asaf, just can’t seem to fit in. Rampie Prefkar is tasked with training CJ on the Hay River delivery route, but Prefkar can’t handle CJ or his attitude.

When Buffalo’s newest Electra, ZFE, lands in Yellowknife with only three functioning engines, mechanic Chuck Adams comes to the rescue to replace a brand-new $29,000 regulator on engine number three. It’s been slow for the airline and delivering a load of building supplies to the RCMP up in Ulukhaktok, NWT, might help keep Buffalo in the air. Spurred by a recent crash landing and two engine fires, an audit team from Transport Canada descends on Buffalo Airways. With their long and tumultuous history with Joe, they demand that Buffalo appoint a new “Accountable Executive” within 72 hours, or risk being shut down. But Joe isn’t about to hand over the keys to the kingdom—not even to Rod, his oldest son. Mikey worries that if they don’t meet the deadline, Buffalo Airways could become Buffalo Spare Parts. Transport Canada isn’t the only thing on Joe’s mind; it’s becoming apparent that Joe’s 16-year-old rescue dog, Sophie, is on her last legs. One morning Joe finds Sophie lying under a plane, unable to stand up. Joe realizes that her time has come—he calls the vet.

Buffalo Joe has been a captain on the daily sked for 34 years and his 70th birthday is next week. Joe might have to stop flying if he doesn’t pass his medical and that could spell the end of Buffalo. Before Joe leaves to undergo five days of medical tests at the Mayo Clinic in Phoenix, Arizona, he calls two rampies, Sam Storm and Jeff Tapper, into his office to greenlight their DC-3 checkflights. Both Jeff and Sam have slogged away for eight months waiting for this chance. But on flight day, Sam is sick to his stomach from eating bad eggs the night before. Sam is not about to let a bad egg beat him and he helps Jeff prep DC-3, LFR. Just before takeoff, nausea wins—Sam has no choice but to back out and there’s no telling when he’ll get another chance. Jeff, on the other hand, has to overcome the jitters that have haunted him ever since he was in a crash landing earlier in the year. Mikey, Rod and his family prepare to greet Joe with a birthday cake shaped like a DC-3. At the last minute, Mikey gets a call that Joe isn’t coming back today; instead he’s decided to celebrate his own way—going for a ride in a classic 1940 Boeing Stearman biplane.

Newly minted copilot Jeff Tapper is excited for his first revenue DC-3, but his inexperience shows when he botches the approach and bounces the landing three times, nearly running off the runway. Meanwhile, for new rampie Prefkar Mony to realize his dream of becoming a DC-3 pilot, he needs to first pass the written IATRA test. He’s been studying for months, but on his first attempt, he fails. With the help of pilot/mechanic Chris Staples, Prefkar retakes the test and passes, but his victory celebration is short-lived when he’s blamed for leaving an expensive shipment of medicine marked “Do Not Freeze” in a courier van during a minus 30 weekend. Later, Mikey and Katie decide to find Joe a new dog and choose Muffy, a three-year-old dog from the SPCA who is ready to leave her pups. They bring her back to the hangar for a test drive. Joe brings DC-3 CUE out of retirement to test fly the plane for Buffalo’s summer sked duty and he brings along Jeff—and Muffy—to see if they’re Buffalo material.

Mikey talks to a 15-year-old aviation buff in England via Skype, who has discovered that Buffalo’s DC3–WZS–flew on D-Day. This inspires Mikey to do something special for the 70th anniversary. He invites Cory to do a tandem parachute jump and finds out that Cory’s grandfather was a paratrooper at the invasion of Normandy. Meanwhile, Mikey takes mercy on Prefkar, working the ramp in Hay River, and offers him a chance for some pilot training on the morning DC-3 freighter. But when the time comes, Prefkar learns that he’s been bumped for pilot David Alexandre. It gets worse for Prefkar when he’s given another chance and this time the fog rolls in. Prefkar might not stick it out at Buffalo. Mikey’s D-Day plans get even bigger when he contacts the Princess Patricia Canadian Light Infantry, who were part of the Allied airborne forces that dropped behind German lines in 1944. He pitches his plan—a reenactment jump from WZS, an actual D-Day plane. But there’s a hitch: the plane needs to pass inspection, and Mikey needs to lose weight to make the cut for tandem jumping. Mikey tries everything he can think of—from juicing, working out with Dan at the gym and even sweating it out in spin class. Cory and Mikey go over what they need to refit DC-3 WZS for a static line jump. Cory is sent on a scavenger hunt for parts in Red Deer and finds a brand-new bracket from the 1940s—but they still need to find the missing rear bracket, and nobody even knows what it looks like.

Mikey shows a veteran Buffalo’s DC-3, WZS, Buffalo’s very own vintage plane from the Second World War. It is being fitted with a special ‘static’ line, which paratroopers will clip onto for a D-Day reenactment jump. But army inspectors tell Mikey a modern military needs a modern line with a winch system in case they need to retrieve a “hung-up jumper”. Cory and Mikey scramble to build the retrieval line before the inspector comes back to test it. But with their bumbling and fumbling, it doesn’t look like they will make the cut. Meanwhile, Chris Staples and some of Buffalo’s pilots head down to Fullerton, California, to Air Combat USA, where pilots get to experience aerial dogfights in real fighter planes. The pilots do yo-yos, spins and pull Gs to out-maneuver their opponent. First up in the dogfights are newly checked-out co-pilot Sam Storm versus longtime co-pilot David Alexandre. Sam wins the fight due to David’s inability to hold down his breakfast. Next up is cocky co-pilot Chris Staples versus his C-46 captain Devan Brooks. But Devan’s many years in DC-3s and C-46s have left him unprepared for the video game pace of dogfighting and he quickly loses 3-0. Finally, the two top guns return to the sky. Sam scores first, but Chris is not about to get beaten.

The Buffalo boys gather in Red Deer for Mikey’s D-Day tribute jump. Joe and Sam scout out the designated military drop zone over Abraham Lake in the Rockies only to discover the canyon is too narrow for the DC-3. So Joe cancels the whole thing—it’s too dangerous. Mikey uses Joe’s own philosophy against him: at Buffalo, there’s always a backup plan. Joe flies out to scout a new location for the drop on the lake but hits bad weather. As Joe is about to scrap the trip, twenty paratroopers from the Canadian and American armies arrive for the big jump and are ready to go. They board WZS and Joe takes off to a site he hasn’t scouted, in weather that just keeps getting worse. As they near the drop point, he finally calls it—no jump tonight. They turn back, with all the troops still on board. Mikey’s only hope is a narrow window first thing the next morning—but only if Joe gives the final okay.
