All around the United States, there are large, difficult-to-reach regions of terrain that, in the case of an outbreak of fire, are often beyond the quick reach of ground-based firefighters.
When fire does break out in terrain like that--and is deemed worth fighting--the U.S. Forest Service may well send in teams of what are called Smokejumpers, groups of highly trained men and women who, when duty calls, load themselves into special airplanes and then jump in to fight the remote fires.
On his Road Trip 2009 project, CNET News reporter Daniel Terdiman visited with the Smokejumpers in Missoula, Montana, and got a chance to see, first hand, their planes, their equipment and their daily preparations.
This is a 1944 Douglas DC-3, one of the most iconic planes of all time. It is used by the U.S. Forest Service as a Smokejumper plane, and can hold a 20-person crew.
A look inside the 1944-era Douglas DC-3 that is used by the U.S. Forest Service as a Smokejumper plane. The plane is kept loaded with equipment and packed parachutes in case it is needed at a moment's notice.
The plane was retrofitted in 1990 and was very recently painted, making it look beautiful and new.
On-board the Sherpa, Smokejumpers who use traditional round parachutes will clip onto this static line so that when they jump, the parachute automatically deploys. The idea is to do the operation as they jump, giving them enough time to pull their backup parachute if the main one doesn't open properly.
These days, many Smokejumpers are using more modern-style square parachutes, and those who use them jump out of the plane without clipping on to the static line, because they will free fall awhile before opening their parachutes.
A sheet of paper posted on board the Sherpa explains the "fashion guidelines" on the plane. The idea is that once in the air, Smokejumpers need to be set to jump at a moment's notice. As well, they need to have control of their gear.
In a special room where the Smokejumpers' parachutes are repaired, several of the 'chutes hang from the ceiling, where they can be inspected to make sure they're in proper shape before being re-packed.
To start their day, the Smokejumpers are given a daily briefing in which they are told about current weather conditions around the West. The idea is to help them prepare and get a sense of where they should expect fires to break out. The drier the region, and the more thunderstorms there are, the higher the likelihood of a fire breaking out in a remote region of terrain.
This is one graphic they were shown on the day that CNET News reporter Daniel Terdiman visited. It showed hot spots and wind patterns.
The day Terdiman visited was wet, as had been many of the previous days. But the Smokejumpers were told to expect drier weather and prime fire conditions within a few days.
Near the Smokejumpers center is a separate U.S. Forest Service facility, the Fire Lab. There, groups of government scientists research everything about fire: how it spreads, predicting modeling about how fires grow and how fuel--wood, undergrowth, etc.--ignites, among other things.
This is an experiment in the Fire Lab designed to study how fuel ignites. The idea is to demonstrate that radiant heat is not enough to catch something on fire, but that actual flames are needed. And here, this device is meant to show the dynamics of flames so that the researchers can study how flames work.
The U.S. Forest Service Fire Lab has begun using a device called LIDAR, which sends a very strong laser beam into the atmosphere, where it hits high-altitude particles of smoke and is reflected back to the device.
By measuring the image that comes back, researchers can study the dynamics of smoke plumes and better understand how high they are, how they're changing over time and more.
