Todin we have this fair treatment of passanjers:

http://www.wtsp.com/story/news/2015/04/ ... /25966873/

Severe weather diverted a Denver-bound flight to Colorado Springs, leaving passengers on the runway for more than six hours Friday.

Republic Airlines Flight 4934, operating under the United Express brand, departed Kansas City International Airport shortly before 6:30 a.m. CST. The airline says severe weather disrupted air traffic in Denver, forcing the plane to land at Colorado Springs Airport about two hours later.

Republic Airlines said the plane then had to park because of a lightning advisory in the area. Two ground stops at Denver International Airport led to further delays.

Passengers on board told 9NEWS they remained on the plane for more than six hours until Republic decided to cancel the flight.

Passengers say the airline offered them the opportunity to leave the plane early and forfeit their seats. Many passengers decided to stay. Eventually, the remaining passengers on board were put on a bus that arrived at DIA shortly before 5:30 p.m.

DIA says about 50 aircraft were diverted to other airports this morning because of foggy conditions. At 2 p.m., the FAA lifted a ground delay activated because of the fog.

Todin it is passanjer appreciation day:

http://www.pbs.org/newshour/rundown/uni ... -security/

The researcher, Chris Roberts, attempted to board a United flight from Colorado to San Francisco to speak at a major security conference there this week, but was stopped by the airline’s corporate security at the gate. Roberts founded One World Labs, which tries to discover security risks before they are exploited.

Roberts had been removed from an earlier United flight Wednesday by the FBI and questioned for four hours after jokingly suggesting on Twitter he could get the oxygen masks on the plane to deploy. Authorities also seized his laptop and other electronics.

Todin it ij pigeons falling from the sky:

1. http://www.baynews9.com/content/news/ba ... shes_.html
The Polk County Sheriff's Office says about 3 p.m. a single engine plane started having mechanical problems in the air before crashing into the neighborhood, near the Lakeland Linder Regional Airport.


2. http://abcnews.go.com/International/wir ... s-30447321

small plane crashed shortly after takeoff Monday from a resort area on the eastern tip of the Dominican Republic, killing all seven people on board, officials said.


3. http://www.redding.com/news/local-news/ ... pilot-ided
Shasta County sheriff’s officials said Monday the sole occupant of a plane that crashed east of Redding Saturday went down intentionally.

They identified the pilot as Zachary Cain Stickler, 34, of Grass Valley.

Sheriff’s officials didn’t specify how they knew the crash was “not an accident.”


4. http://www.timesfreepress.com/news/loca ... rd/299710/
Media report the Mooney 21 crashed around 2:30 p.m. Saturday shortly after taking off from the Winchester Municipal Airport.

Officials say the plane struck some power lines. It apparently landed on its belly, and never flipped over.

Lots more todin. Must be due to 420 phestivitiej.

Wired:

The FBI and TSA have begun telling airlines to watch out for passengers attempting to access their planes' internal navigation networks, despite lacking evidence that anybody's ever actually tried to do so. The Feds are warning aircrews to look for people attempting to access these networks via the public-facing WiFi, through the In-Flight Entertainment systems or by physically connecting to the network ports that everybody now knows are located under their seats.


The warning, posted to the InfraGard website, follows last week's detainment of security researcher Chris Roberts. He tweeted a joke about accessing his United Airlines Chicago-to-Syracuse flight's network to play with oxygen masks but was met by the FBI at the arrival gate instead :twisted: . Of course, just because nobody's been caught doing it yet doesn't mean that such an attack is impossible. Roberts himself admitted to the FBI that he and an unnamed fellow researcher had been accessing the under-seat ports on more than a dozen flights, albeit for innocuous traffic sniffing research. :eek:

"Although the media claims remain theoretical and unproven, the media publicity associated with these statements may encourage actors to use the described intrusion methods," the InfraGard notice states. "Attempting to gain unauthorized access to the onboard networks of a commercial aircraft violates federal law."

Seriously this guy should be strip and cavity searched.

Coming to frisking at US airports haven't you guys getting TSA precheck on the boarding passes? Last few flights I had that and it is a breeze. No removal of shoes, jackets, belts etc and do not even have to remove the liquids. I am not even a frequent flyer. I am enjoying it.

TSA Pre/Global Entry/NEXUS/Sentri/blah blah. All pathetic attempts to create walled gardens and reduce media disturbance from groups capable of organised dissent.

The basic issue is the same -- Ambani may have a 737, but still has to smell the same foul air with dharavi etc slum f@rts. The US approaches are no different and these walled gardens dont work much better than for the ordinary traveller.

Nothing will prevent the "drive by" assault at a layover. Every country has the same type sadists.

A Turkish Airlines plane made an emergency landing at Istanbul’s Ataturk International Airport after hitting “its right side” to the ground during the touchdown, according to state-run Anadolu news agency.

The Airbus 320 aircraft, flying from Milan to Istanbul, took off after the initial attempt to land and made an emergency landing shortly after, Anadolu reported. All 97 passengers were evacuated unharmed, according to a Twitter posting by Turkish Airlines spokesman Ali Genc. The airline started an investigation into the incident, Genc said.

GoAir pilot tells flyer to ‘bugger off’ on health inquiry

NEW DELHI: Indian pilots are increasingly losing their cool these days. In the most recent instance, a GoAir commander insulted a passenger after he expressed concern about the pilot's health.

The commander of the Mumbai-Srinagar flight on Monday (April 27) first reportedly 'forgot' where he was flying the aircraft to while making a public announcement. Then a premium class flyer (GoAir's first two rows are designated business section) saw him come out and ask the airhostess for a strong cup of coffee.

The worried passenger asked the airhostess if the pilot was okay. She reassured him that all was well and that the pilot would speak to him after landing.

"Upon landing, the pilot stormed out of the cockpit and in a fit of rage publicly insulted me and asked me to shut up and leave. (I quote him) 'Don't teach me, keep your stupid doubts and questions to yourself and bugger off'," the Mumbai-based passenger Sajan Raj Kurup said on a social networking site.

Reacting to the pilot's behavior and the alleged outburst, GoAir's chief of flight safety said, "GoAir is committed to passengers' safety, security and comfort at all times. The complaint of Kurup is being looked into with the seriousness it deserves and we have initiated an enquiry into the same."

More trouble for Boeing's "Nightmare"....oops! Dreamliner!

Boeing 787 software problem could lead planes to fall out of the sky if they’re left turned on for too long
http://www.independent.co.uk/life-style ... 19161.html

Issue is just the latest in the Dreamliners' problems, which have also included battery failures and potential hacking attacks
Andrew Griffin
Friday 01 May 2015

Boeing’s huge 787 Dreamliner could see its engines shut down if it is left running for too long, because of a software glitch.

If the plane is left turned on for 248 days, it will go into a failsafe mode that will lead to the plane losing all of its power, according to a new directive from the US Federal Aviation Administration. If the bug is triggered, the generator control units (GCUs) will shut off, leaving the plane without power and loss of control of the plane.

“If the four main GCUs (associated with the engine mounted generators) were powered up at the same time, after 248 days of continuous power, all four GCUs will go into failsafe mode at the same time, resulting in a loss of all AC electrical power regardless of flight phase,” the directive warns.

Boeing is working on a software upgrade that will address the problems, the FAA says. The company is said to have found the problem during laboratory testing of the plane, which is also known as the Dreamliner.

The company told the Guardian that the problem has only occurred in the lab and that all of the planes in service have been turned off and on again as part of regular maintenance.

It is the latest problem to hit the plane, which is also said to be vulnerable to hacking attacks and to have seen difficulties with batteries that have seen them catching fire. Such problems have seen the planes grounded, though they were returned to service shortly after.

Over 250 of the planes have been built, and they are used by companies all over the world including British Airways.

Sirji,

The software problems were "caught" in a lab test. The possibility that the system on an actual aircraft would be continuously powered on for that many days is non existent. :) Nice in theory but not in practice.

The solution in any case is to reset the GCU and the system is back on line immediately after. A reset is what all pilots would first do as a matter of routine. There is no other action possible to bring the generator on line onlee.

This is just a headline grabbing and alarmist report by some airbus funded or motivated guy.

In which airline, in which country, under what management, under what circumstances and for what conceivable reason would any sane pilot or engineer keep the systems continuously powered up for 248 days and for what reason??

The gcus would power down solely on the parameter of time elapsed.

by the determination that a Model 787 airplane that has been powered continuously for 248 days can lose all alternating current (AC) electrical power due to the generator control units (GCUs) simultaneously going into failsafe mode. This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power.


The RAT ( ram air turbine) would have deployed automatically, DC power from other sources like the main batteries as well as emergency batteries would still be available and a simple system reset for each of the GCUs ( taking less than 02 seconds ) would have immediately brought them back into operation.

but as you say, it's "Not entirely impossible." :)

If such an absurd event had indeed come to pass, the regulators would have been well justified in ordering the public execution, by firing squad, of the entire crew, management as well as owners of the airline.

I don't think that this kurup character is as "innocent" as he sounds. The pilot was right to be pissed off, though maybe not publicly.

While the engine running for 248 days is very unlikely, it surely does not inspire confidence in the software that such issues were caught in lab after the plane has been in service. Who knows what other bugs are lurking inside. Aeronautical software as such are to be held to a much higher standard than other non life critical systems.

(unless of course it was intentional and well known and the same is mentioned in the user guidance )

^^^ The source is a 32bit variable overflow. AFAIK, it requires the plane to be powered on to be triggered, not the engines to be on. The generators serve a useful function for a very small time, but this does not mean they are powered on/off manually as needed. The plane is pretty much always powered on, unless intentionally rebooted.

no sane engineer would speed the train up like this unless he wanted to commit suicide. there are easier ways.
me suspects some tampering or SPECTER/HYDRA type tampering + remote control installed so someone overlooking the site could trigger and record the event.
train throttles are like a big lever and needs deliberate use, its not a touch panel where a careless brush could increase speed

must be doing 200kmph for sure

Philadelphia: The Amtrak train that derailed in Philadelphia and a separate commuter train in the vicinity may have been hit by projectiles of some kind shortly before the wreck, a US transportation safety official said on Friday, after investigators interviewed members of the Amtrak crew.

But the Amtrak engineer said he had no memory of anything that happened in the moments leading up to the crash when questioned for the first time about Tuesday night's wreck that killed eight people and injured more than 200 others, said Robert Sumwalt, a member of the National Transportation Safety Board (NTSB).

An assistant conductor told NTSB investigators on Friday that she heard the engineer, 32-year-old Brandon Bostion, talking by radio with the driver of another train from the Southeastern Pennsylvania Transportation Authority (SEPTA). The other driver reported that his windshield had been cracked by a projectile that he believed was either fired from a gun or thrown at the train.

According to the conductor's account, Bostion replied that he believed his New York-bound Amtrak train had been similarly struck after pulling out of its previous stop, Sumwalt said.

It was moments later that the Amtrak train barrelled into a curve at more than 100 miles per hour (160 km per hour), twice the speed limit, in the city's Port Richmond neighbourhood along the Delaware River.

Sumwalt said investigators still have no explanation for why the train was going as fast as it was, and why it had accelerated from 70 mph to 100-plus mph in the 65 seconds before the crash, as was shown on video footage taken by a camera mounted on the locomotive.

The engineer had slammed on the emergency breaking system seconds before the wreck, investigators said.

Sumwalt said on Friday that Bostion, who has spoken with investigators with his lawyer present and was cooperative, told them he had no recollection of doing that, or of anything else from the time the train had departed from its previous stop.

Experts said the train's speed in the moments before the crash raised several questions: Could a technical glitch have caused the locomotive to speed up so rapidly? Would it take a deliberate action by the engineer? Or could human error, a medical issue, or some other factor like clumsiness explain the sudden burst of speed?

Sumwalt said the train, as designed, can only be accelerated by manual control, but the NTSB would examine whether a mechanical malfunction could have caused the train to speed up on its own.

He said Bostion reported to investigators that he had experienced some technical problems on his way south to Washington from New York earlier that day. He did not elaborate.

Saw a new item in today's Al-Hundi about how a cyber security expert, hacked the IFE in a US flight and commanded the plane to fly sideways.. Seems he throttled one of the engines into "climb" mode. :eek: :shock:

he claims he did it in simulation mode...how can it be simulated if he is on a flying plane. one engine going into higher thrust means the plane will yaw and roll to the other side i think.

FAA has already asked all airlines to be alert to pax attempting to access the console of the entertainment systems below the seats

India feeds over 30% of Gulf airlines' US traffic
The most frequent fliers on Gulf airlines’ US routes are Indians, accounting for more than a third of the passengers, according to a Centre for Asia Pacific Aviation (Capa) report.

Gulf airlines are rapidly adding flights to the US. This month, Qatar Airways announced three destinations — Atlanta, Boston and Los Angeles — it will serve next year. Emirates announced a service to Orlando.

The expansion is a source of the escalating trade dispute between Gulf and US airlines and the latter have demanded a freeze on additional flights by Gulf airlines to the US.

The Capa report, released earlier this month, shows passengers from India contributed 36 per cent to Emirates and Etihad’s US traffic in a 12-month period ending August 2014. In the case of Qatar’s US traffic, the share of Indian passengers is 28 per cent.

The second-biggest source for Gulf US flights are their local markets. The UAE contributes 18 per cent to Emirates and Etihad's US traffic. The share of other countries is under 10 per cent except Pakistan which contributes 18 per cent to Etihad's US traffic. For Qatar Airways only nine per cent of its US traffic is local.

What are the economics of this? Does India collect rent? Why not build a world class airline?.....oh yeah, this is India.

It is called "outsourcing".

Should be a familiar term.
