Both DC-10s at Pueblo

Here is a rare photo of the two DC-10 Very Large Air Tankers on a fire assignment at the same place at the same time — Pueblo, Colorado. They were not as busy Wednesday as they have been recently, which could be a result of the milder, more humid weather which led to less intense fire behavior for the last day or two.

DC-10 takes off every six seconds

You may not have heard of Vine. It’s a new social media/networking site that allows you to upload six-second videos, which then keep repeating, forever I guess. That’s about all I know about it. But check out this video of one of the DC-10 air tankers taking off at Mesa Gateway en route to the Doce Fire, which grew from zero to 5,000 acres Tuesday afternoon. When you go to the site you may have to click on the image to start the video.

That video and this one showing Tanker 910 taxiing at Mesa Gateway were shot by Jason Volentine, of KTVK 3TV News in Phoenix, AZ.

Both DC-10s were working the Doce Fire today out of Mesa Gateway. That must have kept the workers at the tanker base busy.

AZCentral has some videos HERE and HERE of air tankers and a helicopter dropping on the fire. The 12News TV station’s Facebook page has some photos of the fire.

A second DC-10 air tanker has been activated. 10 Tanker Air Carrier received a call Thursday night asking the company to have Tanker 910 in Albuquerque by noon on Friday. It is scheduled to depart Southern California Logistics Airport (KVCV) at 10:00AM MDT and should arrive at Albuquerque at about 11:10 MDT.

The company’s other DC-10, Tanker 911, began working on a five-year exclusive use contract two weeks ago and in recent days has been dropping on fires in California, New Mexico, and Colorado. Wednesday and Thursday it assisted firefighters on the Royal Gorge and Black Forest Fires and was reloading at Pueblo, Colorado. Tanker 910 is working on a Call When Needed contract.

During one period last year both of the DC-10s were active at the same time, working for a while out of McClellan airport near Sacramento, California, and Boise, Idaho.

Tanker 910 visited Rapid City and other locations in April. Photos of the Rapid City visit are at Wildfire Today.

Both DC-10s, classified as Very Large Air Tankers, always carry 11,600 gallons of fire retardant, while most large Large Air Tankers carry between 2,000 and 3,000 gallons.

Should very large air tankers be used on 7-acre fires?

A video we embedded in an article on June 7 shows one of the DC-10 very large air tankers making a precision drop using what appeared to be a small fraction of it’s 11,600 gallon capacity, on what was described as a 7-acre fire below Pinal Peak near Globe, Arizona. It generated a fair amount of discussion in the comments, mostly positive, except for one from “Don” who called it “overkill”. “DiggerT” provided a thoughtful response to Don, and I also added my two cents in a comment.

We don’t know why the DC-10 was selected to drop on the fire near Pinal Peak. Maybe it had been dropping on another fire in the area, or perhaps it was the only air tanker available. At any rate, in the video the radio traffic from the lead or air attack plane indicated that he was extremely pleased with the results of the drop.

I am pasting below what I wrote in the comment because it includes a few details about the pricing structure for the seven next generation air tankers that we have not previously covered:

****

“Don, are you aware that the hourly flight rate for the DC-10 on this new exclusive use contract is by far lower than the other six aircraft that were selected for contracts? The nearest competitor is $2,054 per hour more expensive than the DC-10, and the DC-10 is a little more than half the hourly rate for Minden’s BAe-146.

But keep in mind the contract is complex, and the DC-10’s pricing structure, in order to compare apples to apples, is based on delivering 3,000 gallons, approximately the same as the other six aircraft — according to information I received from someone who is very familiar with the contracting process for next generation air tankers. There are additional specifics to cover the DC-10 dropping more than 3,000 gallons.

But as you can see in the bid details, the Total Cost Estimate for the first year, which apparently takes this into account, has the DC-10’s total cost approximately in the same ball park as the others, which are, in millions, $36.4, $36.4, $38.9, $39.5, and $41.3. The DC-10’s was $43.2. But keep in mind that the DC-10 delivers about three to four times more retardant than the maximum capacity of the other next gen air tankers , and six times more than Tanker 40, a BAe-146, if T40 is reloading at Silver City Airtanker Base on a 90 degree day.

And, I have to agree with DiggerT. If there is any potential for a wildland fire to become large it should be attacked with overwhelming force, rather than attempting to fire fire on the cheap. This can save money, property, and lives.

A year ago I wrote my “Prescription for keeping new fires from becoming megafires“:

Rapid initial attack with overwhelming force using both ground and air resources, arriving within the first 10 to 30 minutes when possible.”

Very large air tanker drops on 7-acre fire

Most of us have seen videos of the DC-10 air tankers dropping massive loads of retardant stretched out over thousands of feet of fireline, as seen in this excellent video by Tim Walton, or this one on the Lost Fire, but the video below is very different. It shows Tanker 911 dropping a very small fraction of its 11,600-gallon load on a seven-acre fire below Pinal Peak near Globe, Arizona. It was uploaded to YouTube April 22, 2013 by ir7kbpf.

 

Thanks go out to Johnny

DC-10 air tanker at Phoenix


The news footage above indicates some of the people in the Phoenix area are pleased to have one of the DC-10 air tankers temporarily working out of the Phoenix-Mesa Gateway airport. Some Snake River Hotshots crewmembers detailed there out of Idaho are also interviewed in the piece.

After flying 10 missions on the Powerhouse Fire in southern California over two days, the air tanker flew two missions Tuesday on the Thompson Ridge fire which is spreading rapidly west of Los Alamos, New Mexico. Today they are back on the Thompson Ridge Fire again, reloading out of Roswell, New Mexico.

Those who say the DC-10 can’t be used in the mountains should take a look at this.

It was uploaded to YouTube by Kevin Osborne. From the description there:

In this video, tanker 910 is dropping on the west flank of the Goff Fire (part of the Fort Complex) in late summer of 2012. The video was taken from Tim’s Peak, north of Hwy 96 on the Happy Camp/Oak Knoll District of the Klamath National Forest.

Also, check out these very impressive photos taken by Michael Meadows of the DC-10 dropping on the Powerhouse fire north of Los Angeles June 2, 2013.

10 Tanker Air Carrier moving to Casper, Wyoming

The operator of the two DC-10 air tankers, 10 Tanker Air Carrier, will be moving their base of operations from Victorville, California, to Casper, Wyoming Rick Hatton, the CEO of the company announced today. The company’s headquarters will be at the Casper/Natrona County International Airport in central Wyoming. Mr. Hatton said, “This fantastic operational environment and its central location will allow improved response times to fires in the mountain west region.”

They expect to have both Tanker 910 and 911 available this year, one on an exclusive use contract and the second on a call when needed contract.

Tanker 911 spent some time last summer working out of Casper. One of the fires it worked on was just five miles from the airport. The remarkable photo below was taken on that fire, the Sheep Herder Hill Complex.

The status of 10 Tanker’s contract for a next-generation air tanker that was announced last week is uncertain, in light of the protest that is being lodged by Neptune Aviation. The company does not have a signed contract in hand yet, but if there are no problems, Mr. Hatton expects to have it in a matter of days. If the protest does delay the date when the DC-10 is allowed to begin work, or if the USFS has to start the contracting process over again for the third time, it could be many months before any of the seven next-generation air tankers are seen over fires.

This relocation of the company’s headquarters does not have anything to do with the U.S. Forest Service contracts. Regardless of where the agency decides to base the DC-10 on the exclusive use next-gen contract, the new home of the company will be Casper instead of Victorville.

There are at least eight tanker bases that can accommodate the DC-10 in the western United States with the existing layout of the reloading facilities, according to Pam Baltimore, an Acting Public Affairs Officer for the U.S. Forest Service in Washington D.C. we talked with last year:

  • SBD – San Bernardino, CA
  • MCC – McClellen – CA (Sacramento)
  • MWH – Moses Lake, WA
  • BOI – Boise, ID
  • IWA – Mesa-Gateway, AZ (Phoenix)
  • HIF – Hill AFB, UT
  • HLN – Helena, MT
  • CPR – Casper, WY

Some other bases, such as Rapid City, can accommodate the DC-10 if a portable retardant base is set up. The existing ramp at the Rapid City Tanker Base is too cramped for a Very Large Air Tanker, but there is room on the west side of the terminal for it to be reloaded if a temporary base were set up at that location.

If the DC-10 has to travel farther between a reload base and a fire, that travel distance can be offset to a degree by the 564 mph cruising speed and the 11,600-gallon capacity, equal to about six loads in a P2V.
