I think that statements a bit of a cheap shot - without providing any evidence - at a lot of people who do a lot of hard work to try and define causes behind crashes. There may be some studies, initiated by companies with a vested interest, to get a desired study outcome, but the studies by the universities are generally even-handed.

It's around 12% for car and truck drivers, surprisingly. The University of Adelaide did a study on it in 2008. For pilots, quite likely a lot less, but possibly more than you might expect, too. After a serious aviation crash, often with accompanying fire, it can be difficult to determine precisely whether a medical event precipitated the crash. For older pilots (over 65), the potential of a medical episode causing a crash would be greatly increased.

I can recall a a fatal with a microlight at Beverley, W.A. in the late 1970's/early 1980's. He took off with fuel tank cock turned off. Got up to about 100-150 feet, and came straight back down again. The irony of the incident was, the bloke was a senior air crash investigator with BAS, and he must have seen and investigated dozens of air disasters caused by simple human errors, and a lack of disciplined checklists. Even the best of the best, and some of the most highly respected aviators, have terminated their lives (and others) with incredibly simple errors, related to forgetfulness.

Well, the willy-willies they measured might have only travelled at those low speeds, but I can tell about some personally viewed experiences of mini-tornadoes in W.A., that would indicate wind speeds in excess of 200kmh. In July 1975, at my minesite at Higginsville W.A., I endured a frightening night of howling winds from a major storm that travelled through the Southern Goldfields and S.W. W.A. I was sheltering in a 3-room former railway fettlers hut, a very sturdily built timber building, that was built in 1907, when over-building for strength was the order of the day. I'd transported 4 of these buildings to the mine in 1972, from the nearby Pioneer siding, when the narrow gauge line was upgraded to standard gauge in 1971. I would estimate the consistent winds that night, of around 70-90kmh, with gusts around 100-110kmh. In the morning, I drove S into Norseman, down the Coolgardie-Esperance Rd, and about 10kms S of my mine, a mini-tornado had left a trail of destruction through the native vegetation on the Eastern side of the highway. Now, the vegetation in that area is hefty stuff, big Salmon Gums, decent-size Gimlet trees, and Goldfields Blackbutt trees, interspersed with lighter scrubby trees and bushes. But there was a strip of country there, that looked like someone had dragged a clearing chain between two bulldozers along it. Big Salmon Gums, a metre wide at the base, had been screwed off about 1.5-2M high, leaving shattered stumps. There wasn't a single tree left intact over a length of probably 700-800 metres, and about 100 metres wide. It was total and utter devastation, and it was caused by intense cyclonic wind, and nothing else. I wouldn't have liked to have been in a building in that mini-tornado's path. I've seen the results, in the wheatbelt, of multiple numbers of farm sheds that were destroyed by mini-tornadoes embedded in storms. Some of them were sturdily built from RSJ (I-beam or Universal Beam, or Universal Column, as they're called today), with structural steel trusses. The tornado-like winds just blew them apart. In one case, the mini-tornado picked out a single shed in amongst a group of sheds and a house, and destroyed that single shed, and nothing else. It was like the mini-tornado had simply fallen out of the sky onto that single shed. I have great respect for what concentrated strong winds can do, especially when they're in storms embedded in strong cold fronts, or in thunderstorms.

In W.A., the structural engineer certifies the design as safe and meeting structural standards, so I'd guess the buck stops with him. As to wind speeds, that would have to be a curly one when it comes to a stoush over a collapsed shed. Willy-willies/mini-tornadoes can develop high wind speeds over a small area and a short distance. I can recall my father telling me about seeing a windmill tower screwed up so tightly by a willy-willy, the tower ended up looking like a length of steel wire rope. You'd need an anemometer on the site to be able to get the exact wind speed of any willy-willy.

MB, you're lucky you didn't get, "what's 1/2" in millimetre size?" - and end up being supplied with 12mm bolts. Probably 80% of my equipment is U.S.-design and origin, and I still have the majority of my fasteners in inch sizes and imperial strength grades, and 80% of my tools are A/F or other "inch measure" tools. I was lucky in that I went to high school in the era when imperial measures were still the primary measure, but we were also taught metric measures, too. The kid today seem to be taught no useful life skills, nor even any basic measuring or maths skills. Ever got to a till where the amount owing is say, $11.65, and you're paying cash, and you say, "I've haven't got a tenner, but I'll give you a twenty and $1.65 in coins" - and watched the utter confusion on the youngsters face, as they try to grasp the amount of change to be given? Of course, they've fixed that problem, by providing modified registers, that tell the operator the amount to be given in change.

Marty, note the total lack of cross-bracing in the walls and roof of the shed you linked to. In addition, there's a serious lack of bracing at the apex of the rafters, and at the knee joints with the columns. These are critical areas that come under heavy load with wind gusts. Add in the fact that the lipped C-channel sections in the frame are notorious for twisting and thus losing inherent strength - and that this has to be addressed by using braces between the frame and purlins and girts - but the shed shows none of that style of frame bracing. The minimum requirement for knee bracing - Here is improved knee bracing - and also showing rafter bracing to the purlins to prevent twist - but this design still lacks adequate apex bracing, to my mind.

I'll wager that NVG's played a large part in the crew errors leading to this disaster - and the investigators are almost certainly intent on trying to determine whether they were being worn or not. The training was a simulated night "escape" for VIPS under a simulated major U.S. leadership attack, such as the 911 scenario. Why Are D.C. Plane Crash Investigators Focused on Night-Vision Goggles? - The New York Times WWW.NYTIMES.COM Investigators have yet to determine whether the crew of an Army helicopter was wearing the devices when the Black Hawk crashed into a civilian airliner last week.

As the singular newspaper article (which was reprinted in several other papers of the time) is dependent upon a single persons report - and the fact that there were no follow-up reports, or ensuing stories about Richard Rowes wonderful flying machine, one has to suspect that a grand hoax was being carried out. Even if he had built a flying machine and crashed it, that would certainly have made for further newsworthy reports. Richard Rowe appears to have vanished from any written records after that solitary flying report, and that in itself is unusual, because even if the person kept a low profile, they appear in newspaper family notices at other times.

The Kiwi farmer, Richard Pearse, did get airborne in some fashion possibly prior to the Wright Bros, but it wasn't controlled or sustained flight, unlike the Wright Bros. The American, Gustave Whitehead, who it is claimed, flew before the Wright Bros, is also one of the other largely unsubstantiated early flyers. It's also likely that Whitehead made a few hops into the air, but once again, his versions of his flying exploits, and the affidavits of the small number of witnesses who sighted him airborne, are regularly in dispute. Richard William Pearse, 1877-1953 MY.CHRISTCHURCHCITYLIBRARIES.COM Richard Pearse was a South Canterbury inventor, engineer and farmer. He is famous for being one of the first people on Earth to leave…

I do draw a lot of conclusions indeed, from a grainy photograph - but the similarity of the design of the aircraft in the photo, to a 1909 Farman III biplane, is too much to ignore. People die, and photograph details are forgotten. I believe that's a Farman fuel tank sitting just above the heads of the people in the centre of the photo. It's quite likely that Richard Rowe did build a box-kite glider and got airborne with it. Many people in remote areas did record-breaking things that were never recorded properly, and the Wright Bros are noted for their self-promotion and chasing notoriety. They were fortunate to live in a well populated area with plenty of Press on hand. Farman III - Wikipedia EN.WIKIPEDIA.ORG

He's not a Brenda - he's Brendan, the huge snarly tattooed truckie, and that could create trouble for you, calling him a girl.

I reckon pmccarthy is onto it, the photos are of a later canard-type biplane, and the dress of the ladies (and carrying parasols) is indicative of a European scene around 1910. Cameras were in their infancy in 1889, the Kodak No. 1 was the first camera available to ordinary people in 1888, but it cost a lot of money, and film was also extraordinarily expensive, as it used silver, and silver was a precious metal. There would've been very few cameras in NSW in 1889, and it would've been exceptionally rare for anyone to have a camera readied for an aviation tinkerers attempt at flight, at that time.

Imagine the massive hue and cry if the heli had been full of Govt VIP's or politicians, and a dozen of them died, too? There'd be immediate upgrades of flight planning and ATC operations, on a huge scale.

Original newspaper articles are linked to, below. I'd have to opine Richard Rowe built himself a box kite in the same style as Lawrence Hargrave. However, it's interesting that Rowe got airborne in 1889 and Hargrave didn't fly in his box kite until 1894. There was a lot of interest in building kites that could carry a person in this period, the 1880's. Australian aviation pioneer Lawrence Hargrave celebrated 130 years after first heavier-than-air flight - ABC News WWW.ABC.NET.AU Australian inventor Lawrence Hargrave created history when he was lifted off the ground in a flying device he created in 1894.

I rebuilt the trusses to 8M span with new SHS, because the originals were only 4.8M span, and they were open at the ends and iron ore dust had got into the SHS and caused corrosion. I was originally just going to extend the trusses, it was easier and quicker to just buy some new SHS and cut the brackets off the old trusses and weld them to the new SHS. Yes, you're right, I'm slowing down, too, I'm 75, but you have to do something to keep yourself occupied! I'm fortunate in that I picked up an old Fowler tractor crane for $1500, it's just the shot for lifting stuff around. Not pretty, and it has its limits, but it's still very handy.

Cue Airport is a designated airport, not just an airstrip, so it comes under Federal laws relating to airport operation and ownership. I can't quickly find the ownership status of the land the Cue airport is on, but all the Shire information states that they own and run the Cue airport. There are two land titles involved in the Cue airport location, one inside the other, but it appears the larger outer one comprises the airport land boundaries, The airport land title may be freehold, or it could be simply leasehold - you can apply through Landgate to acquire all the ownership details, but you have to pay a fee, I think it's around $25.00. All the Council planning revolves around plans that indicate the airport is a Shire asset. The airport title is Lot number P092062 93. You'll often find in the old Govt Gazettes, that land was allocated to the likes of "Recreation, Racecourse, Showground and Aerial Landing Ground", with an identifying Govt Reserve number. Many of those Reserves have since been changed to freehold titles or leasehold titles. Leasehold titles are more common in the Goldfields and Pastoral regions of W.A. https://www.cue.wa.gov.au/documents/22/corporate-business-plan-2023-2027 Landgate Map Viewer Plus MAP-VIEWER-PLUS.APP.LANDGATE.WA.GOV.AU

Steel is horribly expensive today, and shed kit suppliers and builders don't care what they charge, they have more work than they can poke a stick at. If the Cue Council is agreeable to the construction of a used shed, then picking up a dismantled shed or used shed frame can be an attractive option. The sheds built from lipped channel are flimsy, they will buckle up in a willy-willy. Go for portal-frame structural steel. I'm currently building an 8M x 12M x 4M shed using modified portal frames made from structural steel, that came from a powerhouse at Koolyanobbing. Stratco want $25,000 for a shed that size, made from pressed metal. I'll do it for less than half that figure and that includes buying all new Z-purlins and girts and new Colorbond sheeting. I found a young bloke in Darlington who does draughting, structural design and council planning, and he's knocking up the plans for the shed, doing the structural calculations, and drawing up all the paperwork for the council, so I can get a building permit. You have to do all this yourself in W.A. today, there was a big change in 2012 as regards building construction permits and procedures. Before 2012, you submitted plans, and the council had to do all the assessments, now YOU have to provide all the engineering certificates, calculations, etc, so the council just has to check it all out on the submitted paperwork and then approve or reject the submission. It reduces the amount of work the council has to do, and throws it all on your shoulders. There's a FB page called "Best Sheds of W.A.", but it's set up by a shed builder who specialises in pressed-metal sheds, and all the followers want the cheapest pressed-metal shed they can get. But the group is full of useful information and contacts. Log into Facebook WWW.FACEBOOK.COM Log into Facebook to start sharing and connecting with your friends, family, and people you know. The wreckage photos shows what happens to pressed-metal sheds, when a decent storm comes through. It can be pretty devastating.

What Skip is better off doing is approaching his Federal MP and asking if a review of the ASIC system is overdue, and whether the ASIC system is still RELEVANT to todays world. All security systems need a regular re-assessment to determine whether they have developed security holes, or whether new threats have emerged that aren't being addressed, and how much of previously-identified threats still exist. There's little to stop a determined evildoer acquiring a fake ASIC card and presenting himself airside to do damage. That's probably the weakest part of the whole ASIC system. The secret to security is having people around who are alert to new people appearing, who shouldn't be in critical locations, and those alert people acting on their suspicions. 90% of crimes are solved by some member of the public becoming suspicious of unusual activity, and alerting authorities or providing vital evidence.

An interesting little story here, showing how even small tweaks to proven designs can add up to improvements in airflow and substantial reductions in fuel costs, over time. It'd be good to find out what level of money and effort they spent on designing and testing of the vanes, just to see what went into them in total, but I guess the effort and money was repaid within a relatively short time frame, with overall fuel savings. Tiny vanes glued to planes promise big savings for US Air Force NEWATLAS.COM A surprisingly simple tweak is making a venerable military transport aircraft more efficient.

iBob, the height drop of the CRJ700 is uninformed conjecture. The NTSB says the airliner was at 325 feet (+ or - 25 feet) and was doing nothing wrong. Crash data suggests helicopter flew too high, plane tried to climb in last second WWW.SMH.COM.AU One second before impact, pilots of the American Airlines plane had a “verbal reaction” and the plane increased its pitch – indicating they pulled back on the controls, trying to climb.
