You guessed it. It's the very same, Very Delicious Big Texas Cinnamon Roll that's been begging for an audience with a compost heap since February 5th, 2009. Dip't if the thing doesn't appear to still be almost edible.
Okay, it's hard, but I'd say 15 secs in the microwave or maybe a minute in a bowl of hot coffee and you're back in bidness, as they say in Big Texas.
Try not to be too concerned about the appearance or texture of the formerly-transparent-now-matte-finished cellophane (which seems to have inflated itself with sufficient pressure to force the aromatic and volatile cinnamon-ey oils through the pores of the Space-Age Polymer that is the wrapper, while qualifying it as a bathtub toy). Just think of the vague stickiness and sweet scent as a tantalizing preview of the taste treat that awaits...
The "Front Porch" flotation device is unfolded and inflated by Pararescuemen and Combat Rescue Officers from the 103rd Rescue Squadron following a jump from the back of a C-17 at Marine Corps Base Hawaii, March 5 2017.
During this training, a rigid inflatible boat (known as a "Hard Duck") was dropped from a C-17 along with several jumpers and an inflatable device known as the "Front Porch".This device is intended to be mated to the Orion spacecraft, and can be used to support astronauts who have made a water landing in the Orion spacecraft following a flight.

This tailings pond is next to 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.
The 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.
Copper and molybdenum concentrates produced at the Continental Mine are not smelted locally - they are not even smelted in America. Concentrates are sold around the world, where material is smelted and the metals are produced. America shipping rocks overseas and buying back the finished product is the behavior of an underdeveloped country - America is not interested in smelting anymore - a sad reality.

I certify this camera as waterproof! ;)
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 trailer was fitted with a slightly longer tongue given the length of the boat. It towed exceptionally well.

One of the sightseeing tours of Singapore is called the Ducktour, and uses an amphibious vehicle used by the US military in the Vietnam war. They were bought by an enterprising travel company and used for these Ducktours where people are taken on a 1 hour trip, starting with a building in the Suntec City. These go through the city and then head for the Singapore river where they go for a short trip around some of the prominent landmarks of the city. It is an enjoyable tour and seemed fairly safe.
In this photo, taken from near the middle of the vehicle, as it starts on the tour, one can see visitors sitting along with the cockpit like driver's seat of the vehicle. Attached to the top section of the vehicle are 2 flotation devices along with some instructions.

When driving in deep snow, we deflate the tires. The pressure is maybe 2-3 psi in this photo.
The low pressure gives a greater surface area on the tire and thus increasing the flotation.
In the belly of the Goose! They only let visitors into a very small area just under/ahead of the wing; you can pay extra for a private cockpit tour (we declined) but can't get at the rest of the interior.
The beachballs were installed for extra flotation in case she sprang a leak during taxi tests.

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.

A passing Helicopter. There was a shortage of Blue Tits so I thought a picture of a Helicopter would help to fill the gap.;-)
This is the vest all put together. Total weight is about 5 lbs, and it is very comfortable and breathable with the mesh and the wide shoulder straps. The straps on my Mustang Personal Flotation Device fit just underneath the breast pockets and are very comfortable and it lays very flat and doesn't interfere with the flight controls or ingress or egress to/from the plane.

No. 73 was the first single axle used for dump/plow/sander combinations. The flotation steer tires were added towards the end of its run at the county and were not original. Photo courtesy of Auctions International.
This duck isn't quite as cute as Pip's ducky floaty ring from last year, but it's made a bigger difference in his swiming style. He's still swimming upright (despite his butt flotation) and splashy on his way out, but once he retrieves the duck he levels out and swims efficiently (see below).

AS332L-1 Super Puma D-HEGG of the Bundespolizei.
On 27 September, 1995, the then G-PUMH departed Aberdeen bound for the Tiffany Platform, 136 nm to the north-east, with the first officer as the handling pilot. While cruising at 3,000 feet amsl and 120 knots, there was a sudden onset of severe airframe vibration Flotation gear was popped with a view to a ditching, but the very experienced commander managed to nurse the Puma and its 15 pax to Longside Airfield (Peterhead, north of Aberdeen) where the helicopter landed on its wheels. The cabin PA system had also failed in flight due to vibration. The 15 passengers and two crew were evacuated without injury.
Subsequent examination of the helicopter revealed that a tail rotor blade flapping hinge retainer had fractured on one side.
The investigation identified the following causal factors:
(1) Maintenance inspections conducted over a period prior to the incident flight did not detect a developing surface crack in the Blue tail rotor blade flapping hinge retainer, despite additional work on the associated tail rotor drive shaft assembly to rectify a tail rotor vibration problem, which was detectable as a trend recording within the Health and Usage Monitoring System some 50 flying hours previously and was the subject of an associated alert five hours before the incident.
(2) The undetected fatigue crack extended during the flight, fracturing one side of the flapping hinge retainer and causing excessive and potentially critical tail rotor vibration.
(3) The fatigue crack had been initiated by fretting and corrosion of the flapping hinge retainer bore induced by abnormal cyclic loading of the retainer, which was attributed to the effects of a defective flap needle-roller bearing during some previous period of the tail rotor drive shaft's life.
(4) The inspection provisions within the aircraft Maintenance Manual and associated Maintenance Requirements did not specify periodic visual inspections of such retainers, since they had been designed and certified on a "safe-life" basis.
The AAIB report made recommendations both to operators and manufacturers that have had a positive influence on the safety of subsequent worldwide helicopter operations!

03_19_06 Not in the plans! I decided to add some reinforcement under what will be the forward seat. The mast comes through here (at the square hole), and the main sail is tensioned down here, and the centreboard raising tackle gets attached. I decided I wanted some beefy backing blocks for the various block and tackle gear to attach to, so I made this brace. It will all hide soon, when the flotation chamber top (aka seat) gets permanently attached.
