The Trouble With India's MIG-21 Fighter Jets - The New York Times
Only a day after the second accident in Rajasthan, a serving officer of the Indian Air Force, Wing Commander Sanjeet Singh Kaila, who himself is a MIG-21 crash survivor, petitioned the courts for the scrapping of the entire fleet. Wing Commander Kaila has contended that flying the aircraft has violated his right to work in a safe environment. The wing commander was involved in a crash during a flight exercise in 2005 after his aircraft caught fire. He delayed in ejecting to safety from his burning aircraft because he was flying over a populated region...
A few months back, India’s defense minister, A.K. Antony, said that out of 29 crashes over the past three years in the Indian Air Force, 12 have been MIG-21 airframes. Two more MIG-21s have crashed since Mr. Antony put out those numbers.

Because of the MIG’s poor safety record, the aircraft has been given grim tags in the public sphere like the “Flying Coffin” and the “Widow Maker.” More than 170 Indian Air Force pilots have been killed in MIG-21 accidents since 1970. These accidents have also resulted in the deaths of 40 civilians.

Belgique: À 80 kilomètres du Nord, la centrale nucléaire de Tihange 1 est «vétuste et dangereuse»
« Tihange 1 est l’une des plus anciennes centrales au monde. Elle a été conçue sur base de principes de sûreté en vigueur au début des années 70 », a pointé M. Mertins. « Les accidents survenus depuis lors à Three Mile Island, Tchernobyl et Fukushima ont démontré qu’une hausse significative des exigences en la matière était nécessaire », a-t-il poursuivi, déplorant à ce titre les nombreux manquements qu’il a constatés à la centrale belge.

Who's driving? Autonomous cars may be entering the most dangerous phase | Technology | The Guardian
“We found that human drivers over-trusted the technology and were not monitoring the roadway carefully enough to be able to safely take control when needed,” said the company in its 2017 safety report.

Ian Reagan from the Insurance Institute for Highway Safety (IIHS) shares Waymo’s caution, although he acknowledges that the safety potential for automated systems is “huge”.

Bilingualism in the Sky | Psychology Today
Flying is the, or one of the, safest ways of traveling so communication in English, even though it is in a foreign language for many, seems to work very well. What are the procedures that are in place to make it so efficient?

The most important aspect is the strictly regulated phraseology and communication procedures that aim at avoiding misunderstandings. That is why it is so critical that all pilots and air traffic controllers adhere to these procedures, which afford multiple occasions to catch errors.

One procedural requirement, for instance, is careful “readback” by the pilot of what the controller has said, and “hearback” by the controller. The latter is supposed to listen to the pilot’s readback and catch any readback errors.

CR 193: The development of a protective headband for car occupants (2000)
In 1997 McLean et al. (1997) demonstrated that energy absorbing headwear for car occupants might be effective in reducing the numbers of head injuries sustained by car occupants. The estimated benefits were greater than the estimated benefits of padding of the upper interior of vehicles to the requirements of the US Federal Motor Vehicle Safety Standard 201. This report investigates the suitability of selected materials for head protection, in the form of a headband that could be worn by car occupants.

A chap at Road Safety Policy, Department of Infrastructure & Transport in Australia was kind enough to send a link to the Australian Government website wherein the study is presented.

I don't think cyclists should be bullied with helmet promotion and threatened with legislation when there exists a very real and present danger to car occupants. I think that the car lobby as well as the general population should be presented with more data and facts about the dangers of driving.

'The bivvy bag probably saved their lives': couple lost in Cairngorms found safe | UK news | The Guardian
CMRT’s leader, Willie Anderson, said the couple were found a few hundred feet below a 1244-metre (4084ft) summit and were very cold. “They misjudged how long their walk would take them yesterday and then the cloud closed in and it started snowing.

“They were a bit disorientated but at least they had a bivvy bag to shelter them. That probably saved their lives.”

Anderson said the pair had tried to find a way off the mountain but were disorientated when a fierce blizzard blew in.

Should Airplanes Be Flying Themselves? | Vanity Fair
In other words, in a crisis, don’t just start reading the automated alerts. The best pilots discard the automation naturally when it becomes unhelpful, and again there appear to be some cultural traits involved. Simulator studies have shown that Irish pilots, for instance, will gleefully throw away their crutches, while Asian pilots will hang on tightly. It’s obvious that the Irish are right, but in the real world Sarter’s advice is hard to sell.

Rules for trusting "black boxes" in algorithmic control systems / Boing Boing
Tim O'Reilly writes about the reality that more and more of our lives -- including whether you end up seeing this very sentence! -- is in the hands of "black boxes": algorithmic decision-makers whose inner workings are a secret from the people they affect.

O'Reilly proposes four tests to determine whether a black box is trustable:

1. Its creators have made clear what outcome they are seeking, and it is possible for external observers to verify that outcome.

2. Success is measurable.

3. The goals of the algorithm's creators are aligned with the goals of the algorithm's consumers.

4. Does the algorithm lead its creators and its users to make better longer term decisions?

Safety case - Wikipedia, the free encyclopedia
A Safety Case is a structured argument, supported by evidence, intended to justify that a system is acceptably safe for a specific application in a specific operating environment.[1] Safety cases are often required as part of a regulatory process, a certificate of safety being granted only when the regulator is satisfied by the argument presented in a safety case. Industries regulated in this way include transportation (such as aviation, the automotive industry and railways) and medical devices.

Aviation. VIDEO Le pilote d'un Airbus A319 se serait assoupi en survolant Nantes. Info -
le vol en question était parti d'un aéroport espagnol pour rallier Bruxelles. Alors que l'A319 survolait la ville de Nantes (Loire-Atlantique), des contrôleurs aériens français ont tenté d'établir un contact avec les pilotes. En vain. Au bout de dix minutes, un Rafale aurait alors pris en chasse l'avion belge, permettant d'entrer en communication avec ses pilotes.

Toujours d'après le quotidien belge, l'enquête a déterminé que le pilote principal de l'Airbus s'était assoupi

Near Miss Project
This one’s a short piece to introduce the project from my perspective. I’ve been researching cycling since 2008 (alongside my other work, now including leading a Transport MSc). A couple of recent research projects have looked at people’s views on cycling with children, and gender and age equity in cycling.

I’m really excited about studying near misses, for several reasons.

From Out of Nowhere | Beyond the Kerb
We build our event horizons through a function of speed, positioning, anticipation, attention and more. We choose to build those horizons far away or as close. We choose whether to imagine people who may be on the road and events that may befall them. And just as we may choose to ignore them we may equally to choose to always – always – anticipate them.

Beyond those horizons of perception lie all of our Nowheres.

La vitesse bientôt limitée à 30km/h dans Paris ? – Europe1 | Nouvelles
Anne Hidalgo a présenté lundi soir un plan anti-pollution afin d’améliorer la qualité de l’air dans la capitale. Et parmi les mesures de la nouvelle maire, la limitation de vitesse à 30 km/h dans les rues parisiennes, grands axes exceptés, promet d’être la plus commentée. La plus combattue aussi.

the crowd: Hillsborough and ‘crowd control’
These days, the leading crowd event safety experts agree that many problems in crowd events – including some of the most well-known crowd disasters – are due to problems in crowd management. Examples would example the failure to plan for sufficient space for the size and flow speed of the crowd, and the failure to communicate adequately with the crowd.

This kind of analysis, which moves attribution for crowd disasters away from the supposedly inherent psychological problems of the crowd (whether of ‘convergence’ or ‘submergence’) to deficiencies in management and planning, is a positive development. It suggests that crowd disasters are not simply something that ‘just happens’ from time to time due to the inherently primitive psychology of the crowd; rather, crowd disasters are preventable through improvements in knowledge about, and hence to the practice of, crowd safety management.

if it had still been 30mph I would have probably killed a small child this morning.

He ran out in front of my car. I was able to stop but only just.

Ideas: Who to Believe: Auto Speed and Accident Mortality
I wrote: "I guess the key study your search missed is Leaf and Preusser's 1999 literature review: which concludes that the risk of death and injury does indeed rise with the speed of the colliding vehicle.
Those of us fortunate enough to have had a basic scientific education find this an unsurprising result: the kinetic energy of a moving object increases with the square of its velocity. The more energy imparted to the body in the event of a collision, the greater the damage."

If this sounds slightly snarky, then it is. This was a very low quality blogpost and attracted a very low quality discussion. But as I'd found this post as part of my own search to nail the 20mph--10%, 40mph--90% collision mortality statistic (I realise I'd never seen it formalised in a scientific publication, or if I had, I've forgotten), and I thought maybe some reader might be saved from ignorance by encountering a comment. (Hence the extended tagging after the dccomment tag).

Herbal Supplements Are Often Not What They Seem -
Canadian researchers tested 44 bottles of popular supplements sold by 12 companies. They found that many were not what they claimed to be, and that pills labeled as popular herbs were often diluted — or replaced entirely — by cheap fillers like soybean, wheat and rice.

Public health anthropologist uses ethnography to improve farmworker safety | Penn State University
Snipes works mostly in the Rio Grande Valley in Texas. For periods of three months to a year, she latches on with a group of farmworker families as a participant observer, moving along with them from crop to crop. "I have picked just about everything," she says. "Apples, cherries, hops, asparagus, broccoli, raspberries, onions, squash, watermelon, cotton…" Along with picking produce, she's gathering data: conducting interviews and focus groups, administering surveys and epidemiological assessments, and collecting biomarkers of pesticide exposure. "I want to have a comprehensive view of what's happening in their lives," she says.

Snipes brings to the field a special understanding that goes beyond her academic training. "My own grandmother worked picking cotton," she says, "so I have some understanding of the hardships, and I have those stories to share."

Among her findings is a common belief that danger attaches to the physical form that a pesticide takes... "So if it's wet, a spray that people can feel landing on their skin, it's seen as harmful, and there is great concern. If it's dry, however, there is little or no concern. They call it 'powder,' and consider it almost like dirt."

A similar distinction is made between hot and cold. "Just like my grandmother, many farmworkers believe that if you wash your hands with cold water you'll end up with arthritis, or rheumatism. This type of belief is very common cross-culturally," Snipes says, "but in this context, it may have health impacts... where workers are given cold water both to drink and to wash the residues of pesticide powder from faces and hands, they may rather wait until they get home to a hot shower, believing that cold water is to be avoided, and that powders aren't really harmful anyway. "That decision means eight to 12 hours of additional exposure."

Permis Piéton - on n'est jamais aussi bien protégé que par soi même !
"Il est utile de rappeler que, jusqu'à 6 ans, l'enfant ne peut faire attention qu'à une seule chose à la fois : s'il court après un ballon ou s'il veut rejoindre ses parents de l'autre côté de la rue, il ne pensera qu'à cela et pas aux voitures. À partir de 7 ans, il commence à pouvoir tenir compte de plusieurs informations simultanées, mais ce n'est que vers 11-12 ans qu'il sera vraiment capable de prévoir l'évolution des situations et donc d'anticiper."

The idea that one should need a permit from the police in order to walk
around is really a very telling metaphor of the pass western society has come to, but there it is. The analysis of epidemiological risk is interesting nevertheless...
