Hawker Nimrod's were invented in the 1930's to operate from Royal Navy Aircraft Carriers, they were Fighters designed to Defend the Fleet from Enemy Aircraft. Originally known as the ''Norn'' the Nimrod was developed from the Hawker Fury Biplane Fighter, it has longer wings, and was fitted with special equipment, such as 'flotation boxes' in the wings and fuselage. The type entered service with the Fleet Air Arm in 1932, replacing the ''Fairey Flycatcher''. All Nimrod's could be adapted to become either Landplanes with wheel undercarriage or Seaplanes with twin floats.
In 1933, a total of 36 MK.II Nimrod's were built, they were equipped with more powerful Engines, swept wings, arrester hooks to help them to land on shorter Aircraft Carrier Decks, and other modifications. Nimrod's remained in front-line service with the Fleet Air Arm until 1939 and were declared obsolete in 1941.
Hawker Nimrod MK.II K3661 was built in 1934 and issued to No.802 Squadron in 1936, she was probably sent to RAF Lympne in 1939 as a ground instructional airframe and was later transferred to the Air Training Corps in Ashford, Kent. Found on a rubber tip in Ashford in 1972, the Aircraft fuselage, wings and tail unit were stored by the RAF Museum at Henlow and Cosford until sold to ''Aero Vintage Limited'' in 1991.
Restoration for the ''Historic Aircraft Collection'' began in 1992 using several small parts from K3661 held by the Kent ''Battle of Britain Museum'' at Hawkinge and a Rolls-Royce Kestrel Engine from Canada. A large number of technical drawings were obtained from Denmark, were local production of MK.I's had been planned but never begun. K3661 returned to the air at Duxford in 2006 and is the only airworthy Nimrod MK.II in the world.

Regent's annual Primary Swim Gala took place on Friday 16th March. The day began with Year 1 and 2 students competing in a series of fun relay events involving various flotation devices and balls. Yellow House gained the most points for the Year 1s and it was Red House who took the lead for the Year 2s. Next it was the turn of our Year 5 and 6 students, who competed using more traditional swim strokes. This was a hotly contested affair, with all the Houses gaining lots of points. However it was Yellow House who were victorious for the Year 5’s and 6’s combined. By the afternoon it was time for the Year 3 and 4 students to complete their races. Once again the points were shared fairly evenly amongst the Houses. However it was the Green Crocodiles who collected the most wins and points to go towards their entire House total score. Once all the points were added up Green House raised the Swim House Cup aloft to rapturous applause from the students in their House. A very well done to all the students who took part; a fun and very wet day was had by all.

Moomba Boats @MoombaBoats is digitally chronicling the first production build of the new Mojo 2.5 wakeboard boat with daily build photo posts. This series of blog posts and photos galleries will illustrate the superior production processes that make a Moomba boat.
Today is the fourth production day of this new Moomba wide-bow wake boat. We have seen the deck created and pulled from the mold. Today we will see the structure of the hull completed in the mold with the sub floor installation and then we will see it pulled out. After the hull has been pulled it will be closely inspected. The deck and the hull together are starting to look like the Mojo.
After the CompSys Stingers have been laminated inside the hull the sub floor of the Mojo is installed. This first floor is affixed to the stringers and the inside of the hull with WeldOn, a chemical adhesive that forms a stronger bond than fiberglass. WeldOn actually changes the molecular structure of the two materials it is joining to make them literally one part. So at this point in the Moomba Mojo construction the hull, stringers and sub floor become one.
Now we come to a step that is foregone by most of our competitors. At this stage in production a Moomba boat, no matter which model, is injected with Closed Cell Flotation Foam beneath the floor. The injection of this foam insures there are no open air voids in the structure of the boat. This process dampens noise and vibration as well as improves the boat structural integrity. This is a large part of why Moomba boats are the quietest value performance boats in the industry. The Coast Guard does not require this flotation foam in boat models over 20 feet in length. This is why many of our competitors skip this step to save time and money. Moomba injects all of their models with full flotation foam. We don't build boat this way because it is easy. We do it because it is the right way.
Once the sub floor has been installed and the WeldOn is properly set, the hull is ready to be pulled from the mold. When this separation occurs we will see the exterior gel coat of the first production Mojo hull for the first time.
Just like the deck the hull has an incomparable shine even right after it has been pulled. This amazing finish is thanks to meticulous conditioning and preparation. But even a nearly perfect surface requires scrutiny at Moomba. After the hull is pulled it is closely examined under lights to reveal any imperfection no matter how small. The items, if any, are marked for attention and addressed before the boat leaves the factory.
Tomorrow this Mojo will be in rigging ready to except its Indmar engine. Tune in to the Moomba Mojo Build Day 5 on the blog for that powerful experience.
One of the many great things about the individuals who work on the production line at Moomba Boats, is their dedication to continued improvement. They are constantly looking to better themselves and the processes they execute everyday. The results are evident in the new Mojo 2.5.
Stay tuned to the Moomba Boats Blog for more photos and production process descriptions of the first production Mojo 2.5 build. Your Mojo could be next. Moomba is brand you!
Pararescuemen and Combat Rescue Officers with the New York Air National Guard's 103rd Rescue Squadron, 106th Rescue Wing, supported by the Hawaii Air National Guard's 154th Wing, 204th Airlift Squadron, conduct personnel recovery training in order to test the new "Front Porch" flotation device for NASA's Orion Crew Module.
This training was conducted alongside NASA personnel at Joint Base Pearl Harbor-Hickam, Hawaii during Exercise SENTRY ALOHA March 7, 2017. A major element of this two week TDY is to participate in a joint NASA and Defense Department mission to evaluate recovery techniques and gear that will be used to recover NASA's Orion spacecraft, the next generation of American space vehicle.

The pirogue is a flat bottom canoe made for calm shallow waters and swamps. I built this one from Uncle Johns.com plans. The spruce and redwood flotation compartments are my own design. Effective, but they added alot of weight and difficulty in cartopping. Also, this design weathercocks badly in the wind...but then it was never designed for choppy waters.
Hopefully the Wood Duck 12 will solve these problems.

Premier John Horgan toured the Highland Valley Copper Mine — located approximately 17 kilometres west of Logan Lake and about 50 kilometres southwest of Kamloops. HVC produces both copper and molybdenum concentrates through autogenous and semi-autogenous grinding and flotation.
Angela calmly told us where the emergency exits were, how to breathe through the mask should we lose pressure in the cabin, how to use the seat cushions for flotation should be have a water landing, and more that we didn't really think about, or we wouldn't be so calm.

These pipes deliver waste rock material to a tailings pond near the Continental Mine in Butte, Montana (= “Richest Hill on Earth”; = "The Mining City"). The Butte Mining District has produced gold, silver, copper, molybdenum, manganese, and other metals.
The area's bedrock consists of the Butte Quartz Monzonite (a.k.a. Butte Pluton), which is part of the Boulder Batholith. The Butte Quartz Monzonite ("BQM") formed 76.3 million years ago, during the mid-Campanian Stage in the Late Cretaceous. BQM rocks have been intruded and altered by hydrothermal veins containing valuable metallic minerals - principally sulfides. The copper mineralization has been dated to 62-66 million years ago, during the latest Maastrichtian Stage (latest Cretaceous) and Danian Stage (Early Paleocene). In the supergene enrichment zone of the area, the original sulfide mineralogy has been altered.
The Continental Mine was started in 1980 by the Anaconda Copper Mining Company - it is currently owned by Montana Resources. The mine targets a low-grade copper and molybdenum deposit on the eastern side of the Continental Fault, a major Basin & Range normal fault in the Butte area with about 3500 feet of offset. The mine's rocks consist of BQM with disseminated copper sulfides, plus copper- and molybdenum-bearing hydrothermal veins that intrude the BQM. Minerals at the site include chalcopyrite, molybdenite, malachite, azurite, tenorite, and cuprite. The latter four minerals are secondary copper minerals, produced by alteration of the primary copper sulfides.
In 2010, the Continental Mine was making 50,000 to 52,000 tons of ore each day. This mine can operate down to an ore grade of 0.1% copper. Most of the mineralization is disseminated copper, but veins are also present. Two stages of mineralization occurred in the Butte area - a porphyry copper system and a main stage system with large veins. The bottom of the porphyry copper system is ~ less than 12,800 feet below the surface. Veins peter out at 5600 to 5800 feet below the surface. At the Continental Mine, veins are small - they're veinlets less than 6 inches wide.
Mining is done 24 hours a day, 365 to 366 days per year. There's 1 to 2 days of down time at the mill. During those days, mining stops and waste material is moved. The ore:waste ratio is 8:10 (= strip ratio). The alluvial overburden consists of 7 paleosol horizons, including some caliches - the lime content results in an average pH of 8. The caliche material can be used to treat acidic materials.
This mine has 14 shovels and 15 trucks. A large Bucyrus shovel can load a 240-ton truck in three passes. The mine's benches are forty feet tall. Blasting is done with ANFO - ammonium nitrate and fuel oil. 0.65 pounds of explosives are used per ton of rock. The mine uses ~45 megawatts of power per day, which is about the same as the city of Butte itself.
Continental Mine ores are crushed in two stages. The crushed ores are then sent to the mill, where they are ground down to the fineness of talcum powder. Flotation and lime are used in processing. Sulfides are collected. 1% of the mined material goes to the concentrator. 99% of mined material becomes tailings. The tailings powder is wet (33% solid and the rest is water) and piped uphill to a pond. The tailings pond water has a pH of 10. Water from the pond is recycled to make tailings slurry. 27 million gallons a day enters the pond. An earthen dam around the pond is designed to withstand a powerful earthquake.

The 2P15 12.50 Penzance - Plymouth crosses the viaduct over the River Tiddy. It always seems to be low tide when I come here for photos. Lovely tranquil spot. There were some guys on a boat in the foreground inflating big yellow flotation tanks either side of their vessel which sort of spoiled my preferred angle so I had to move along the quay a bit.
September 2014 saw the completion and delivery of a Phil Bolger-designed Work Skiff for my brother. The interior and exterior were painted, flotation foam placed in the appropriate compartments, non-skid sand added to ensure good footing, the trailer obtained and fitted to the boat, and the boat delivered 1,800 miles to northwestern Wisconsin.
The gunwales, though made of lumberyard douglas fir, held up well under the straps, though I think I'd reinforce the friction points with a layer of fiberglass tape and epoxy on the next boat (or this one, after we use it a bit).
Lesson learned: check the trailer light lenses at >every stop< to ensure they're screwed on tightly. Better yet: use thread lock to ensure they stay on!
