Wip Wiplinger, the Man Who Put Wings on the Water and Turned a Crop Duster Into a Firefighter

Robert “Wip” Wiplinger, the founder of Wipaire and the man behind the Wipline float and the Fire Boss firefighting aircraft, has passed away. Over more than six decades, he built one of the world’s most respected seaplane float and aircraft modification companies and connected two worlds most people never think of together - bush flying and aerial firefighting. His floats still hold working airplanes above the water from Alaska to Australia, and his scooper conversion is fighting wildfires around the globe.

Who Was Wip Wiplinger?

Wip founded Wipaire around 1960 in South Saint Paul, Minnesota, on the Mississippi River. Over the following 60-plus years, the company grew into one of the most respected float and seaplane modification firms in the world.

Its flagship product is the Wipline float. To the untrained eye a float looks simple - a pontoon you bolt under an airplane so it can land on water. In reality, it is one of the most demanding pieces of engineering on a light aircraft.

A float has to be light enough to preserve the airplane’s useful load, yet strong enough to absorb the punishing forces of water landings. Its shape must let the aircraft climb “up on the step” and break free of the water’s grip - a discipline of hydrodynamics entirely separate from how a wing generates lift. On an amphibious float, it also carries retractable landing gear, wheels, and brakes tucked inside a structure that spends its life getting wet.

Wip understood all of it. His floats earned a reputation for being tough, efficient, and beautifully built.

Why Wipline Floats Matter to Seaplane Pilots

Walk any seaplane base in Alaska, across Canada, through the Minnesota lake country, or into the island-hopping operations of the world, and you will find Wipline floats holding airplanes up out of the water - Cessnas, de Havilland Beavers, Otters, and the rest of the working bush fleet.

Why this matters for pilots: If you have ever considered a single-engine sea rating, flying into a lake cabin, or working a floatplane operation, the equipment that makes that possible didn’t just appear. Someone had to design it, certify it, and stand behind it. Wip was among the handful of people in the entire industry doing that work at the highest level.

What Is the Fire Boss, and How Does It Fight Fires?

Wip’s second great contribution had nothing to do with recreation or the bush. It had to do with fire.

Wildfire seasons have grown longer and more intense across the western United States, Canada, southern Europe, and Australia. When a fire breaks out in rough country, a truck often cannot reach it - only an aircraft can arrive in time.

For decades, aerial firefighting meant large, expensive converted airliners and purpose-built tankers dropping retardant. Effective, but costly and not always available where needed. The alternative is the scooper: an airplane that skims across a lake, scoops water directly into its tanks on the move, and carries it straight to the fire - no ground crew, no ramp refilling.

This is where Wip’s two worlds met. Take the Air Tractor AT-802, the largest of the big, rugged single-engine turbine agricultural airplanes built in Olney, Texas, designed to haul heavy loads of spray or fertilizer low and slow, day after day. Put that airplane on a set of Wipaire amphibious floats with a built-in scooping system, and the agricultural workhorse becomes something entirely new.

That airplane is the Fire Boss.

It flies to a wildfire, finds the nearest lake, river, or reservoir, descends, and skims the surface - scooping hundreds of gallons of water into its tanks in seconds without ever stopping. It then climbs out, drops the water where crews need it, and turns around to do it again. Quick turns, close to the fire, at a fraction of the cost of the big tankers.

The Fire Boss is now a genuine tool of the trade, working in the United States, Europe, and South America - anywhere there is fire and water nearby. The reason it can land on a lake at speed, survive it, and repeat that hundreds of times a season comes back to the floats. Back to Wipaire. Back to Wip.

More Than Floats: A Full-Service Aviation Company

Wipaire was never just a float builder. Over the years it became a full-service operation offering aircraft modifications, gross weight increases, interiors, avionics, maintenance, and restoration - the kind of shop where a tired airplane could come out better than it left the factory. And it stayed rooted in South Saint Paul, in a state that takes its floatplane flying seriously.

Keeping a company like that alive for six decades is no small feat. Aviation is a brutal business: certification is slow and expensive, liability is heavy, and the market for any single product is small. Larger, better-funded, better-known companies have come and gone in that time. Wipaire endured because it was built on genuine engineering and genuine service - and because the person at the top understood both the airplanes and the people who flew them.

Why this matters for pilots: This is what a healthy general aviation industry looks like. It isn’t only the big airframers - it’s the modification shops, the float builders, and the family companies that solve specific problems for specific pilots. Those people are the reason our airplanes can do more than they left the factory able to do.

The Through-Line: Where the Airplane Meets the Water

Water runs through Wip’s entire career - the float that lets a Beaver land on a wilderness lake, and the scooping system that lets the Fire Boss pull a load from a reservoir. The place where an airplane meets the water is among the least forgiving environments in all of flying. Water landings break airplanes, corrosion eats them, and the forces are unrelenting. To master that environment for a lifetime, and to build a company the whole seaplane world trusts, is a genuine achievement.

An analyst’s note, offered as opinion rather than fact: the Fire Boss may be one of the most underappreciated aircraft in the modern fleet. It lacks the drama of a jet tanker and rarely makes the evening news. It simply does the work - cheaply and effectively - and saves ground that would otherwise burn. It exists because someone who spent his career thinking about how airplanes meet water looked at a firefighting problem and saw an answer no one else had built.

As of the 2026 fire season, Fire Boss aircraft are expected to be back at work again - scooping and dropping over terrain most of us will never see. It is a legacy that doesn’t sit in a museum; it goes to work.

Key Takeaways

Robert “Wip” Wiplinger, founder of Wipaire, has passed away, leaving a legacy spanning seaplane aviation and aerial firefighting.
He founded Wipaire around 1960 in South Saint Paul, Minnesota, and built the Wipline float into an industry standard found on Cessnas, Beavers, and Otters worldwide.
The Fire Boss pairs an Air Tractor AT-802 with Wipaire amphibious scooping floats, turning an agricultural airplane into a low-cost, fast-turnaround wildfire scooper.
Fire Boss aircraft operate across the United States, Europe, and South America and are expected to fly again during the 2026 fire season.
Beyond floats, Wipaire is a full-service shop offering modifications, gross weight increases, avionics, maintenance, and restoration - a model example of the small companies that keep general aviation strong.
