Residents of Kentucky reporting that this year’s flooding is the worst they’ve seen, with the Governor saying the death toll will hit double digits.  State officials declared it to be catastrophic, and admitting they don’t have the labor to adequately respond to calls for rescues.  Next door neighbor West Virginia is sending help.

The West Virginia National Guard is sending two UH-60M Blackhawks and two UH-72 Lakota rotary wing aircraft, and their crew.  They are rom Company C, 2-104th General Support Aviation Battalion (MEDEVAC) and Company B, 1-224th Security and Support Aviation Battalion, based out of Williamstown.

The flooding is ironic as earlier this month the Kentucky Army National Guard was deployed to one city that was facing sever water shortage.

Interestingly, and you could call it perfect timing, back in February 2022, the Montana Army National Guard revealed plans to lease helicopter hanger space in the Eastern part of the state, due to the fact there was no National Guard search and rescue (SaR) presence in that part of the state: “If you look at a map of the U.S., that area Montana, southern Montana, northern Wyoming, that area is the largest area in the U.S. that does not have military aviation coverage.”-Colonel Rob Oleson, Director of Aviation and Safety, Montana Army National Guard

On 15Jun2022, additional militia personnel were sent to Caribou County, to assist local law enforcers by operating seven checkpoints in the Red Lodge area.

Grissom Air Reserve Base in Indiana, firefighter survival school video by Technical Sergeant Joshua Weaver:

On 21MAR2022, a ‘four alarm’ wildfire started on Fort Devens, Massachusetts: “The difficulty is that the fire burns in an impact area. This impact area is about 650 acres that have been used by the Army for training since 1918, creating an area of unexploded ordinances and munitions, meaning firefighters can’t enter that area safely and have to work from the outside and from isolated fire roads that run through the impact area.”-Timothy Kelly, Devens Fire Chief

Fort Sill, Oklahoma, conducted prescribed burns of 406 acres: “We plan these as much as a year in advance. We follow a strict set of parameters that not only protect us, the firefighters, but everyone on Fort Sill and the local communities.”-Jay Young, Chief of Fire Department Station 4

Beavercreek Township Fire Department, Ohio, held an intense three-day exercise at the Dayton Fire Department Training Center, and they asked Wright Patterson Air Force Base firefighters to officially judge the training: “We’ve asked Wright-Patterson Air Force Base for some of their chief officers to come over and help evaluate our performance. They are a disinterested, third party who have similar training and similar incident-management techniques. We’re regular mutual-aid partners, which means that if we have a major incident and we don’t have enough resources, they’ll send resources to support us and then vice versa.”-David VandenBos, Beavercreek Fire Chief

This is the final year of a multi-year U.S. Department of Defense led wildfire study. Fire behavior and smoke analysts from the U.S. Forest Service, the U.S. Geological Survey, the National Weather Service, University of Florida and University of Washington, descended upon Fort Stewart, Georgia, to observe annual prescribed burns, as part of the study.  Joe O’Brien, a project leader with the U.S. Forest Service, says that despite what was taught in the past, fires are a necessary part of keeping wildlands healthy, plants grow back quickly (I remember back in the 1970s and 1980s being told by California officials that it took decades for plant regrowth after fires, yet I saw for my own eyes that plants/trees had recovered within a year after wildfires in the San Bernardino mountains) and the net effect is actually carbon reduction: “If you don’t burn these forests, you lose all the species that depend on this kind of forests…..  You’ll see regrowth occurring almost immediately….  The net amount of carbon in the atmosphere is being reduced by the formation of this char.”

The Connecticut Air National Guard revealed a new plan to integrate military and civilian fire fighters, it is known as ‘regionalization’.  Local civilian fire departments say it’s all about the labor shortage: “The old philosophy was, it’s our jurisdiction, we’ll take care of it. Nowadays, we’re so short on staffing, we can’t do it by ourselves anymore.”-Jim Griskewicz, Deputy Chief of the Windsor Fire Department

Connecticut Air National Guard photo by Master Sergeant Tamara R. Dabney, 10DEC2021.

Connecticut Air National Guard hosted a regionalization training event on Bradley Air National Guard Base.  They also revealed a new computer automated dispatch (CAD) system which eliminates the need for humans to operate: “Once we switched dispatch centers in July 2021, we were able to switch to a newer CAD-based run card system. If a 911 caller calls into a dispatch center and says it’s smoking in the facility, starts that run card for the resources that are required for that type of incident. They automatically would be dispatching these units without us having to call four or five different departments….”-Chief Master Sergeant Robert Cross, Connecticut Air National Guard

The information that came with this pic stated the DC-8 was being used to test alternative fuels in California, January 2009.

The DC-8-72 uses a plethora of electronic equipment for remote sensing scientific studies in archeology, ecology, geography, hydrology, meteorology, oceanography, volcanology, atmospheric chemistry, soil science and biology.  The name of the organization/university conducting the study is sometimes painted on the forward section of the fuselage, underneath the Dryden Flight Research Center name.

Michigan militia flood rescues

“I heard about the flooding about 30-minutes after the first dam collapsed.  I received a call from my command around 11pm last night to come in right away and have been working since.”-Private First Class Lydia Humphrey, 1073rd Maintenance Company, Michigan Army National Guard

In northern Michigan the Edenville and Sanford Dams failed between 19-20 May 2020, but the state’s National Guard was already activated for the CoViD-19 lock-downs, so response time was fast.   130 of the 1-thousand activated Guard personnel were diverted to flood response.

Officials also said evacuation warnings had been heeded by most residents so there wasn’t much rescuing going on.

The U.S. Army Corps of Engineers, Detroit District, is now figuring out how to prevent more dam failures in Midland and Gladwin counties, due to severe weather.

Back in April 2020, the U.S. Army Corps of Engineers reported that The Great Lakes were at record water levels and that significant erosion and flooding was ongoing.

On 17MAY2020, Invest 90L became Tropical Storm Arthur.  This is the sixth year in a row that a Tropical Storm developed in May.

USAF photo by Technical Sergeant Christopher Carranza, 16MAY2020.

During ‘invest’ flights the WC-130Js fly at low altitudes (500 to 1,500 feet, 152 to 457 meters) to determine if there is a closed circulation.  Once a system becomes a storm the WC-130Js fly at higher altitudes (5,000 to 10,000 feet, 1524 to 3048 meters), and fly through the eye of the storm several times during a mission. Dropsondes are launched from the aircraft into the storm, which then communicate with the National Hurricane Center via satellite link.  (What’s a storm tracking Dropsonde?)

U.S. Navy keeps old U.S. Army Boat-Truck afloat

The Lighter Amphibious Resupply Cargo-5 tons capacity (LARC-V) was developed by the U.S. Army in the 1950s.  Just short of 1-thousand of the aluminum hulled boat-trucks were made, almost half being intentionally destroyed as the United States ended its occupation of Vietnam.  About 1-hundred are now privately owned.  Perhaps in response to concerns about climate change, the U.S. Navy ordered a SLEP (Service Life Extension Program) refurbishment of the versatile LARC-5, and since 2006 has accepted 42 of the upgraded decades old swimming trucks.

In September 2019, the U.S. Navy used LARC-5 Duck Boats to transport equipment that would allow Navy ships to transfer fuel oil to Alaskan villages onshore.  It’s part of preparations for an expected major natural disaster that could cut-off remote villages along the U.S. Pacific coast.

Hurricane Harvey: MARINES USE AMPHIBIOUS COMBAT TANKS TO SAVE LIVES!

Bare Metal: NASA Trucks

1942 FORD FIRETRUCK RETURNS TO SERVICE WITH THE USAF!

WHAT DOES IT TAKE TO MAINTAIN A FLYING MILITARY FIRETRUCK?

Bare Metal: NASA Trucks saving the Trucking Industry

According to NASA, it was in 1973 that one of its employees became intrigued with how high speed tractor-trailer rigs created massive ‘suction’ as they drove-by slower moving vehicles.  In 1975 a study showed that big-rig trucks moving at 55 miles per hour (the national speed limit at that time) displaced as much as 18 tons of air for every mile traveled.  About half of the truck’s horsepower was needed just to overcome aerodynamic drag.

After leasing a cab-over tractor-trailer from a Southern California firm, Dryden (Edwards Air Force Base) researchers added sheet metal modifications that look very much like what you see on today’s big-rigs. They rounded the front corners and edges, and placed a smooth fairing on the cab’s roofs and sides extending back to the trailer. During the investigation of truck aerodynamics, the techniques honed in flight research proved highly applicable. By closing the gap between the cab and the trailer, for example, researchers discovered a significant reduction in aerodynamic drag, one resulting in 20% to 25% increase in fuel economy.

NASA estimates that its contribution to the ground vehicle industry has reduced fuel consumption by as much as 6-thousand-8-hundred gallons per year per vehicle!

Researchers also installed a boat tail structure on a passenger van.  During the tests, the vehicle’s sides were fitted with tufts, or strings, that showed air flow. The investigators concluded that rounding the vertical corners front and rear reduced drag by 40%, with at a  decrease in the vehicle’s internal volume by only 1.3%. Rounding both the vertical and horizontal corners cut drag by 54%, resulting in a 3% loss of internal volume. Adding a faired underbody helped reduce drag by about 15%.

In a kind-of control test, the passenger van was first covered with a sheet metal box with intentionally squared corners.

It was discovered that simply rounding the corners resulted in a huge reduction in aerodynamic drag.

One of the most effective, and simple, NASA discoveries is saving the trucking industry big money on fuel costs today; the ‘Airtab’.
