Mendocino Air Tanker Squad
The Mendocino Air Tanker Squad (MATS) is a flying fire fighting team working to protect the Mendocino National Forest. Joseph Bolles Ely, the Fire Control Officer formed it In 1956. History The impetus for this unit occurred on July 9, 1953, when fifteen men were killed while fighting the Rattlesnake Fire, in the Alder Springs area of the Mendocino National Forest. The tragedy prompted forester to look for better ways of fighting fires. Joseph Ely was fighting a fire in the Angeles National Forest at the time of the Rattlesnake Fire. According to his son Frank, Joe became passionate about making firefighting safer for his men. The idea of dropping water from airplanes had been considered for many years and but no experiments had led to the regular use of airplanes to drop water. Ely had the idea to use agriculture pilots who were adept at spraying liquids over crops. He approached Floyd H. Nolta, already an experienced and innovative agriculture and stunt pilot.

Bentonite
Bentonite ( ) is an Absorption (chemistry), absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation through the porosity of volcanic ash beds, which converts (devitrification) the volcanic glass (obsidian, rhyolite, dacite) present in the ash into clay minerals. In the mineral alteration process, a large fraction (up to 40–50 wt.%) of amorphous silica is dissolution (chemistry), dissolved and leaching (agriculture), leached away, leaving the bentonite deposit in place. Bentonite beds are white or pale blue or green (traces of redox, reduced ) in fresh exposures, turning to a cream color and then yellow, red, or brown (traces of oxidation, oxidized ) as the exposure is weathered further. As a swel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Douglas A-26 Invader (designated B-26 between 1948 and 1965) is an American twin-engined light bomber and attack aircraft, ground attack aircraft. Built by Douglas Aircraft Company during World War II, the Invader also saw service during several major Cold War conflicts. A limited number of highly modified United States Air Force aircraft served in Indochina Wars, Southeast Asia until 1969. It was a fast aircraft capable of carrying a large bomb load. A range of guns could be fitted to produce a formidable ground-attack aircraft.Wheeler 1992, p. 82. A redesignation of the type from A-26 to B-26 has led to confusion with the earlier and unrelated Martin B-26 Marauder, which had already been withdrawn from service when the designation was reused.

Douglas DC-6
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles. The DC-6 was known as the C-118 Liftmaster in United States Air Force service and as the R6D in United States Navy service before 1962, after which all U.S. Navy variants were also designated as the C-118. Design and development The United States Army Air Forces commissioned the DC-6 project as the XC-112 in 1944. The Army Air Forces wanted a lengthened, pressurized version of the DC-4-based C-54 Skymaster transport with more-powerful engines. By the time the prototype XC-112A flew on 15 February 1946, the war was over, the USAAF had rescinded its requirement, and the ...

Consolidated PB4Y-2 Privateer
The Consolidated PB4Y-2 Privateer is an American World War II and Korean War era patrol bomber of the United States Navy derived from the Consolidated B-24 Liberator. The Navy had been using B-24s with only minor modifications as the PB4Y-1 Liberator, and along with maritime patrol Liberators used by RAF Coastal Command, this type of patrol plane was proven successful. A fully navalized design was desired, and Consolidated developed a dedicated long-range patrol bomber with tests begun in 1943, designated PB4Y-2 Privateer. The first version of the Privateer flew in September 1943 with production versions arriving in March 1944. In 1951, the type was redesignated P4Y-2 Privateer. A further designation change occurred in September 1962, when the remaining US Navy Privateers (all having previously been converted to drone configuration as P4Y-2K) were redesignated QP-4B. Design and development The Privateer was externally similar to the Liberator, but the fuselage was longer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grumman F7F Tigercat
The Grumman F7F Tigercat is a heavy fighter aircraft that served with the United States Navy (USN) and United States Marine Corps (USMC) from late in World War II until 1954. It was the first twin-engine fighter to be deployed by the USN. While the Tigercat was delivered too late to see combat in World War II, it did serve in reconnaissance roles. The Tigercat primarily saw action as a night fighter and attack aircraft during the Korean War. Designed initially for service on ''Midway''-class aircraft carriers, early production F7Fs were land-based variants. The type was too large to operate from older and smaller carriers, and only a late variant (F7F-4N) was certified for carrier service. Design and development Based on the earlier Grumman XP-50 that was eventually canceled, the company developed the XP-65 (Model 51) further for a future "convoy fighter" concept. In 1943, work on the XP-65 was terminated in favor of the design that would eventually become the F7F.Dorr and Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman TBM Avenger
The Grumman TBF Avenger (designated TBM for aircraft manufactured by General Motors) is an American World War II-era torpedo bomber developed initially for the United States Navy and Marine Corps, and eventually used by several air and naval aviation services around the world. The Avenger entered U.S. service in 1942, and first saw action during the Battle of Midway. Despite the loss of five of the six Avengers on its combat debut, it survived in service to become the most effective submarine killer and most widely-used torpedo bomber of World War II, sharing credit for sinking the super-battleships and and being credited for sinking 30 submarines. Greatly modified after the war, it remained in use until the 1960s.Wheeler 1992, p. 53. From 1942-on, production of the Avenger (in fact nearly three quarters of its the total production) was subcontracted to a purposely established division of General Motors: the Eastern Aircraft Division.
