Snohomish
County Fire District 19’s two Neoteric hovercraft have been deployed in the rescue
and recovery efforts at the Oso, Washington mudslide since the initial alarm
and will remain active during the coming days as water levels lower and more
area becomes available to search.
Those of
us following the tragedy on the news cannot even begin to grasp the vast wasteland
created by the mudslide. Trent Nunemaker, President of Fire District 19 and a
primary first responder in the effort, has reported in from the scene, giving
us a better understanding of the devastation created by one of the worst
landslides in U.S. history.

The number
of confirmed fatalities has now reached 24, with 22 still missing. One of the
rescuers on Trent’s team was personally affected, losing family members when his
home was swept away by the slide. “Fortunately,”
Trent says, “the amount of support we
have received from the local community and from around the nation has been
overwhelming.”
Trent
describes the scene: “The only way I can
describe the debris field is that it looks as though a bomb has gone off. Most
first responders have seen the damage done when a car hits a tree at high
speed. Try to imagine what would happen if a forest of trees hit a neighborhood
at 100 mph. Everything from vehicles to homes have been completely destroyed
and spread across a half mile debris field.”
Rescuers
have been hampered by rain all week and are contending with treacherous
conditions such as sewage, household chemicals and gasoline and propane
containers. When first responders and search dogs leave the site, they must be
hosed down by hazardous materials crews. As an on-site spokesman said, “We're worried about dysentery, we're worried
about tetanus, we're worried about contamination.”
Trent goes
on to explain the unequaled utility of rescue hovercraft in such situations: “The slide area contains several hazardous
environments - impenetrable debris fields, large clay islands, and a debris
field that is completely flooded by the backed-up Stillaguamish River. Initially the river was completely blocked by the slide, which caused a large
portion of the debris field to flood. But our hovercraft can navigate through
floating debris and logs, so we’re able to cross the flooded valley and access
the debris field. Unfortunately, much of the debris contains nails and other sharp building hardware which tend to catch on the skirts of the hovercraft. We've overcome this by hovering low in the water and pushing such debris aside with the fiberglass body of the craft."
He adds, "These Neoteric craft are able to quickly and safely access almost any environment.”

Besides
their search and rescue role, hovercraft serve additional functions in disaster
scenarios like this one. Trent elaborates, “We're also using the hovercraft to transport and retrieve personnel and rescue
equipment to and from the debris field and other areas that are hard to access
by any other means. They’re an excellent platform to rapidly reach our teams
working out of smaller unpowered inflatables which have incorporated search
dogs.”
He
continues, “During one day’s search
operations I was assigned Safety Officer for water operations and used one of the hovercraft to keep track of all the watercraft operating in
the debris field. The hovercraft was very well-suited for this job as it
allowed me to quickly reach crews in the field to assist in the event of an
emergency.”
"We're constantly coming up with new uses for our hovercraft," says Trent. "Recently we've worked on techniques to lower our craft by ropes down steep embankments. This has proven to be very successful and allows us to take advantage of more launch sites. Our hovercraft have become a
critical tool in our swiftwater rescue team’s operations. Every second counts
when it comes to water emergencies and the hovercraft allow us to access all
our district’s waterways quickly and safely."
The
Washington mudslide is not the first time the hovercraft have been a critical
tool for Snohomish County. In May of last year, the craft were called in when a
portion of an Interstate 5 bridge collapsed, dropping vehicles and passengers
into the Skagit River 60 miles north of Seattle.
The important role of hovercraft in search and rescue operations like these helps us understand that these unusual craft have a far greater purpose than simply serving as recreational vehicles or golf carts. Hovercraft are critical rescue equipment that, time and time again, save lives and protect first responders in dire situations where no other vehicles can perform.
