The Woodbury Fire 12 miles east of the Phoenix suburbs became very active on the northeast side Tuesday beginning at about 2 p.m., sending up another large column of smoke that blew off to the northeast. It added another 3,894 acres to bring the total up to 44,451 acres.
On Wednesday fire crews are preparing for the possibility of the fire moving north towards Roosevelt and east towards the Pinto Mine along Pinto Canyon. Firefighters will be using burnouts and existing black lines to divert fire from the Reavis Ranch, Roosevelt, and mining operations. They will continue the preparations along 500 KV power lines to make them more defensible, masticating brush and building bulldozer lines where appropriate.
The smoke is expected to spread to the east on Saturday, becoming noticeable in Southern New Mexico and Western Texas.

On March 29 a K-MAX helicopter at Grand Canyon National Park lifted two vehicles out of the inner canyon that drove off the edge in 2017. The National Park Service didn’t provide any details about how or why the vehicles ended up there, or if anyone was in them at the time, Thelma and Louise style.
Apparently this is a recurring project, as you can see in the video from 2009:
And in other Grand Canyon aviation news, the park’s contract helicopter has a new paint job. The MD-900/207E recently returned to the park after having all the old paint sanded off by hand. The sanding and painting took about 6 weeks.
The drone that landed, caught fire, and ignited what became a 335-acre fire in Northern Arizona was battery-powered and approximately 16″ x 16″, a spokesperson for the Coconino National Forest said. The operator reported the fire and was later cited for causing timber, trees, slash, brush, or grass to burn. The spokesperson did not know exactly how the drone caught fire.

Just a couple of hours ago we wrote about how proud the Department of the Interior is of their drone program (as they should be). And there’s no doubt that Unmanned Aerial Systems can play an important part in improving situational awareness for wildland firefighters.
But today investigators have determined that the preliminary cause of a wildfire north of Flagstaff is a drone that landed and caught fire. At 3:25 p.m. MST Tuesday the Coconino National Forest said firefighters had stopped the spread of the resulting wildfire after it burned 335 acres near Kendrick Park by Forest Roads 514 and 524.
There is no information yet about the operator of the drone or if it was powered by a battery or gasoline.
All of these photos were provided by the Coconino National Forest.
Thanks and a tip of the hat go out to Tom. Typos or errors, report them HERE.
While CAL FIRE embraced the DC-10 and used it extensively until the state ran out of money, the USFS was very skeptical, to say the least. The agency is extremely slow in making any changes to their aerial firefighting program. They appear to have a bias against Very Large Air Tankers, like the DC-10 and 747, and water-scooping air tankers, even though they have all been used very successfully by other agencies. Finally after it had proven itself over a few years, a DC-10 received a Call When Needed contract, and later an Exclusive Use Contract, and Incident Commanders and Air Operations personnel were often very happy to see it in the air over their fires.
A lot of people, including some who leave comments on this site, have viewpoints about the effectiveness and performance of specific models of air tankers. Some of them are based on indisputable facts, and others are opinions developed from…. something else. So, like reading political news, be careful when consuming information.
On July 24, 2012 we wrote an article on Wildfire Today with quotes from evaluations of a DC-10 that were written by lead plane pilots hours after they had directed it on fires. The DC-10 almost always carries at least 11,600 gallons of retardant, rarely having to reduce the load because of density altitude issues.
Here’s the article:
Evaluations of Tanker 911, one of the DC-10 very large air tankers
We have seen the written evaluations of Tanker 911, one of the DC-10 very large air tankers, for some of the retardant drops the aircraft completed on fires in Arizona and Utah in June and July. The forms were signed by individuals identifying themselves as lead plane pilots.
The evaluation form consists of two parts; a narrative section, and assigning a grade for specific aspects of performance: Reload Turn Times, Maneuverability, Steep Terrain Operations, Drop Patterns, and Uniformity of Coverage. All of the grades were “Above Average” or “Exceeded Expectation”.
Here are the details that were hand written in the narrative section on the forms:
Poco Fire, Phoenix, Arizona; Gallons Delivered 11,700 x 6; June 16-19, 2012
All drop patterns were good and uniform. Flat and steep terrain – excellent performance in all profiles.
CL [Coverage level] 6 utilized in timber and mixed brush.
Quantity and mass of load delivered allowed for higher than standard drop altitudes to minimize exposure in challenging terrain and still achieve good pattern on the ground.
Quantity delivered also means 1 pass, 1 exposure instead of 7 from a legacy platform carrying 2,000 gallons!
Very uniform and consistent pattern on the ground. Very accurate starts. Performed some split loads as needed.
Fox Fire, Tucson, Arizona; Gallons Delivered 11,700 x 2; 2 loads; 3 drops; June 18, 2012
1 – CL 6 – Split Load – Started and stopped to tie in a road in front of structures. Very accurate start and stop. Last 2,000 gal reinforced first drop.
2 – CL 4 – One drop. Excellent coverage! It would have taken 6 or 7 loads from a legacy platform to get same length of line.
Quick effective line production.
Six Shooter Fire, Globe, Arizona; Gallons Delivered 11,700; 1 load; 8 drops; June 17, 2012
This was an initial attack fire. The location of this 5-acre fire, 1,500 to 2,000 ft below a ridge line, necessitated a substantial decent profile to get over the target on speed and altitude. The DC-10 was very capable and provided excellent coverage on and around the entire fire. The fire was successfully stopped at the same perimeter when the tanker dropped!
Excellent drops and performance.
Shingle Fire, Cedar City, Utah; Gallons Delivered 11,700 x 4; 4 loads; July 2-3, 2012
Good coverage and line production. Excellent pattern on the ground and saved lots of time vs utilizing smaller aircraft. We would not have been able to get the line needed done without this tool.
Long turn arounds loading at [illegible; looked like “IVA”, “IWA”, or “IUA”]. 2 hour flights but dollars/gal still comperable considering speed and gallons!
**** DC-10 air tanker delivers 373,600 gallons of retardant
One of the DC-10 air tankers has dropped about 373,600 gallons of retardant during 33 sorties on seven wildfires in Arizona and New Mexico over the last 10 days. The fires were: Little Bear fire, 257 fire, Grand fire, Poco fire, Six Shooter fire, Fox fire, and 177 fire. They were all in Arizona except the Little Bear which was in New Mexico.
Eight of the nine air tankers currently on exclusive use contracts with the U.S. Forest Service are 50+ year old P2Vs designed for maritime patrol. Their average retardant load is 1,948 gallons according to a 2007-2009 air tanker study. If all of those 373,600 gallons the DC-10 dropped in those 10 days had been delivered by a P2V it would have taken about 192 round trips to the fires.
A man was arrested in Prescott, Arizona for flying a drone into the airspace near the Goodwin Fire that as of Friday had burned over 25,000 acres southeast of the city.
Gene Alan Carpenter, a 54-year-old from Prescott Valley, is accused of endangering 14 aircraft and ground personnel with a “substantial risk of imminent death or physical injury” by flying a drone near or over the fire. All firefighting aircraft had to be grounded for about an hour on Wednesday, June 28.
In 2016 Arizona passed a law making it illegal to fly a drone that interfered with emergency or law enforcement efforts. It is likely that a Temporary Flight Restriction was in effect over the fire at that time which would make it a violation of federal law for any aircraft to invade the space without permission.
If a drone collided with a firefighting helicopter or fixed wing aircraft it could cause great harm especially if it hit a windshield or engine. And if the aircraft crashes, killing the pilots, firefighters on the ground would also be in danger from the falling debris.
The safety of firefighters is compromised when all of the helicopters, lead planes, air attack, and air tankers are grounded, preventing the aircraft from slowing the fire so that firefighters can move in and construct fireline. When aircraft and ground personnel disengage, homes and private property could be destroyed that might otherwise have been saved with an aggressive firefighting attack. Some air tankers when grounded by an intruding aircraft can’t land with a full load of retardant, so they have to jettison it, wasting thousands of dollars worth of the product.
On June 24 multiple witnesses reported seeing a man operating a drone at the Goodwin Fire standing next to a white van.
Below is an excerpt from an article at 12news:
The sheriff’s office said based on witness information, drone descriptions and photos from Carpenter’s website showing drone views of the Goodwin Fire, deputies began searching for him.
Carpenter was arrested Friday afternoon after an off-duty deputy spotted his van on Willow Creek Road in Prescott. The drone was found in the van and seized.
Detectives are meeting with federal officials Monday to discuss additional charges based on the federal statutes regarding temporary flight restrictions.
Mr. Carter is in custody at Yavapai County facilities at Camp Verde, Arizona charged with 14 counts of endangerment, all felonies, and one misdemeanor.
The video describes the process of reloading the DC-10’s with fire retardant at Phoenix Gateway-Mesa airport while they were fighting the Goodwin Fire 80 miles northwest of the airport. For a while this week all three DC-10 Very Large Air Tankers were working out of the tanker base and dropping on the Goodwin Fire.
