The Grumman HU-16 is still wingless in Arizona, where Michael Manousakis and his mechanics are trying to get the plane flying again. And the “Albatross” is not the only flying object that the “Steel Buddies” have to contend with. Thousands of “swift bees” are making themselves at home at Glendale Airport. The insects, which are a protected species, have to be relocated without further ado. But beware: only twenty stings from this highly aggressive species are fatal to humans. Meanwhile, a large delivery from the US army arrives in Peterslahr.

The aggressive bees have been relocated. But Michael Manousakis and his full-blooded bees in the US state of Arizona can't breathe a sigh of relief just yet. Because the moment of truth is approaching in Glendale. An experienced inspector is taking a close look at the “Steel Buddies'” amphibious aircraft at the airport. Is the Grumman HU-16 still airworthy or does the corrosion on the wings of the 60-year-old aircraft pose too great a risk? Thumbs up or thumbs down: The expert's verdict will determine the progress of “Mission North Pole”.

In this episode, Michael Manousakis receives a visit from Poland in the Westerwald. His old friend and business partner Marian has traveled to Peterslahr with two freshly restored “Mutts”. After a thorough inspection, however, it turns out that some defects were overlooked during the work. There is a confrontation between Marian and the “Steel Buddies” in the company yard. And Michael Manousakis is caught between the two sides. Because one of the vehicles has already been sold. A regular customer of “Morlock Motors” wants to pick up the car shortly.

Michael Manousakis bought a 40-ton crane from a scrap yard in Seville a year ago. Now the “Steel Buddies” want to remove the monster in Spain. But the project does not go as smoothly as planned. Even getting there turns out to be a challenge. Before the team can start work, there are various problems to solve. And after that, the full-blooded mechanics unpack the cutting torch. After all, the team has to dismantle components before the crane can roll along European roads on a low-loader.

The company yard in Peterslahr has been chaotic for years. Finding vehicles or spare parts in the chaos costs time and nerves. But this is now set to end. Michael Manousakis wants to bring order with an app that he has programmed especially for this purpose. But is it even possible to keep track of all the items on the Morlock Motors site? Or will his boys be annoyed and throw in the towel? Meanwhile, sparks fly as Bogdan and Alex cannibalize an ice cream van.

The “Steel Buddies” set off for Arizona again to get their problem child up and running. The Grumman HU-16 Albatross is standing on the airfield in Glendale without wings. The mechanical experts want to repair a wing. So far, so good. But then it turns out that the troops need a special steel part that was made in the USA. Now “Miss Morlock Motors” is needed. Julie uses her contacts to get a replacement. Meanwhile, in the Westerwald, a customer wants to fulfill his long-awaited dream of a cool pick-up.

The sheet metal sticks firmly to the wing. This work process cost the “Steel Buddies” time and nerves. And the next challenge is not long in coming. Now the team from “Morlock Motors” in the US state of Arizona has to take care of other components. Because oil is dripping from a propeller on the more than 60-year-old amphibious aircraft. Meanwhile, Andy, Ingo, Bogdan and Marek have completely different worries in Peterslahr. The quartet has to stack two containers. A crane and meter-long steel cables are used in the Westerwald.

Michael Manousakis is planning a trip to the highest peak in Arizona with his troop. The mountain hike is intended to prepare the “Steel Buddies” for the planned North Pole mission and test their stamina. But even the journey there is difficult due to the cold in Flagstaff. The school bus, the preferred motorhome of the full-blooded mechanics, won't start. Meanwhile, in the Westerwald, a roadblock intended to keep unwanted visitors away from the company premises has to give way. The metal colossus weighing several tons is a thorn in the side of the emergency services.

Michael Manousakis welcomes the “Steel Buddies” on board his Douglas DC-3. The destination of the trip is Vienna. There, the mechanics experts want to take a close look at an old crane. Julie is also on board for the trip to the Austrian metropolis. But the flight turns into a turbulent rollercoaster ride. The group reaches the Prater by the skin of their teeth. And it remains to be seen whether the trip to the neighboring country will pay off financially in the end. Because although the crane costs nothing, it could still turn out to be a loss-making business.

The “Steel Buddies” are guests at Europe's biggest air show in Zeltweg. For the “Morlock Motors” team, the event in Austria is an absolute highlight. Because at “Airpower” you can marvel at historic propeller aircraft and ultra-modern high-tech flying machines. Michael Manousakis also goes into raptures. Because, as we all know, his great passion is flying. Meanwhile, Tim's childhood memories are awakened. And Julie runs into an extreme sportsman who caused a worldwide sensation with a jump from the stratosphere.
