An inside look at aerial firefighting — the high-stakes game of combatting the West's unprecedented wildfires on high
An inside look at aerial firefighting — the high-stakes game of combatting the West's unprecedented wildfires on high

As a harsh wildfire season burns across the western US, an important method of fighting those fires soars above.
In addition to ground crews, aircraft help slow the spread of the fires in an impressive orchestration of work.
Helicopters scoop water out of lakes and pools, airport crews help converted passenger planes refill, and amphibious airplanes skim across water sources to negate the need for refills.
Business Insider recently got a personal look at how aerial crews in Washington State are combatting the flames.
Across the western US, firefighters have been busy tackling one of the worst wildfire seasons to date. The year has been unprecedented in both size — accounting forsome of California's largest ever, for example — and sheer scope, with dozens upon dozens of fires burning simultaneously.
Ground personnel are critical to turning the corner on any fire, but groundwork alone often isn't enough to get the edge on a notoriously vicious and unpredictable enemy. That's when the folks on the ground look up to the sky for a little help.
Enter aerial firefighting, the high-stakes game of fighting fire from on high.
If you've watched the evening news of late, you've likely seen them hard at work. Dramatic video of passenger-sized jets flying low over flaming mountain ridges to lay down bright red retardant, or dropping water seemingly just feet over the roofs of threatened houses abound.
Business Insider recently had the opportunity to get an inside look at the work those folks have been doing up in Washington State.

With wildfires burning across the western US, the ground crews often need a little help from on high to fight them. That's where aerial firefighting comes in.

Business Insider recently got an inside look at how that goes down in Moses Lake, Washington, where fire bombers — including former passenger planes — have worked to slow the spread of the wildfires.

It is just one in a system of such bases dotted throughout the western US, creating a network of coverage that leaves even some of the most remote fires little more than a 30-minute flight away.
Jeremy Dwyer-Lindgren
Moses Lake has the additional distinction of being one of the few bases nationwide that can handle the very largest aerial tankers, such as the Douglas DC-10 or Boeing 747 Supertanker.

Today, though, the big jets are tasked elsewhere, leaving only two smaller Convair 580 tankers on the ramp.

The 1950s-era propeller planes, operated by Canadian aerial fire-fighting company Conair, were taking a break after a busy morning working the then-enormous Cold Springs fire in the central part of the state.

A break in the action provides a rare look inside the airplane. It's been almost completely gutted, the original ribs and frame clearly visible.

Some supplies occupy the very rear of the plane, while crew essentials like a change of clothes are closer to the cockpit.

This particular tanker began its life in 1953 as Convair 340 piston-engined passenger plane, flying for the likes of Braniff and Allegheny.
Jeremy Dwyer-Lindgren
It was upgraded to the turboprop 580 version, most likely in the 1960s, and converted to a fire bomber many years later.

While the cockpit isn't 100% original, it bears many of the same original instruments and panels as well as some modern upgrades.

The tanker is, as noted, on the smaller side. The very largest, the Boeing 747 Supertanker, can carry 19,200 gallons.

The Convair, though, carries closer to 2,100 gallons, released by a simple button on the yoke.

The tour is broken up with a radio report that an Aeroflite Avro RJ-85 is inbound for a refill and a refuel.

Its home base had become too busy.

Minutes later, the former passenger turned fire bomber jet is pulling into a parking spot on the ramp.

The crews get to work right away.

A team of two runs the retardant hose out to the plane, attaching it to the port and loading in some 3,000 gallons into its tanks.

Filled with retardant and a fresh load of fuel, the jet lumbers long down the runway before lifting off and turning eastward toward its target.
Jeremy Dwyer-Lindgren
While it might seem counter-intuitive, tankers rarely drop retardant onto the fire itself.

Instead, they'll work with ground crews to drop strategically ahead of the front, creating lines that are intended to direct the course of the flames or slow the advance.

That work was evident a few days earlier, September 4, in the small mountain town of Naches, Washington, where the nearby Evans Canyon Fire had been encroaching at an alarming rate.

On arrival that afternoon, it was already clear that the Convair crews from Moses Lake, along with a few others, had been busy.

The efforts had seen the fire beaten back over the mountain, but work was still left to be done.

Overhead, a small plane, which was working as an incident command and control platform, circled the edges of the fire, high and out of sight.

Today's command plane isn't the only one loitering in the area.

Sure enough, it isn't long before a tanker is inbound, the same Conair Convair 580 we'd meet a few days later.

When you need good ole water directly onto the fire, though, there are a few other time-tested airborne tools of the trade.

The most common are helicopters.
Jeremy Dwyer-Lindgren
Exceptionally versatile, they can drop hundreds of gallons of water directly onto the fire with surgical precision, shuttle firefighters and equipment, or help evacuate folks injured or unable to escape.

Unlike tankers, helicopters have no need to go back to a specific base to refill. They can scoop or suction up water almost anywhere it can be found; rivers, lakes, drainage basins, even backyard swimming pools.
Jeremy Dwyer-Lindgren
They can operate with tanks, as the Bell UH-1 Huey did on the Evans Canyon fire, or with buckets, like the converted army Blackhawks did over the Sumner Grade Fire in western Washington.

That also enables them to douse the fire far more frequently.
Jeremy Dwyer-Lindgren
While they carry a fraction of the volume of the large aircraft, helicopters may be able to squeeze 10 or more precision drops in an hour.

A tanker, by comparison, may be limited to one or two.
Jeremy Dwyer-Lindgren
Somewhere between tankers and helicopters lies another valuable tool, the Canadair CL-215T Super Scooper.

A custom-built water bomber, the amphibious airplane earns its name by scooping 1,600 gallons of water out of nearby lakes, reservoirs and depositing it directly onto the fire.
Jeremy Dwyer-Lindgren
It can even grab water from the ocean if need be.

When refilling, the airplane never completely lands — instead skimming across the top of the water at a low speed until its tanks are topped off. The entire process takes an impressive 12 seconds, filled entirely from the surprisingly small scoops, seen below.

The crews have been busy, hitting fires and lakes throughout Washington State and northern Oregon.

Together, these aircraft, helicopters, their crews on the ground and in the air help keep our communities safe from wildfires.
