  1. looking under the hood I would take a 320 over a 737 any day.

    The systems integration on the 737 is a mess of old and really old technology and now they are attempting to ADD new technology.   Sure it's a workhorse but it no longer tried and true.  Its a mess.

    the 320 is designed with the systems integration at the forefront and it works.  It IS now the tried and true.

    That isn't the point. If a doctor believes that a certain medication could help why is he/she not allowed to prescribe it. 

    I believe hitting you in the foot with a big rock will cure your headache.  Should I do it?

    you cant prescribe meds based on beliefs.  you need the science and doctors do NOT have that in theri repertoir

     

  3. Based on the Russian performance in Ukraine to date, I have my doubts that any threat of nuclear attack is reliable.

    They have commited fully 75% of their standing military to Ukraine and have not performed as well as one would think.  Who is to say that Nukes and Hypersonic Missiles are not just empty threats because no one has been maintaining the the munitions.  All of the money was funnelled to the Oligarchs.  

    I believe nothing from Russia

    The mighty 737 has done it's bit, now it's time for something new.  Of course, the passengers want cheap airfare but that's not what I was talking about or what I said.  What I said is that passengers would better served with a new design.

    A new design could/would incorporate a better ventilation system maybe with humidity control, probably slightly wider seats, possibly a bigger door, certainly a more ergonomic flightdeck and galleys which would improve the service and safety.  The list goes on and on.  TBH, the 737 has been skating by many required safety advances on the basis it's pre-existing certification and this has most definitely not served the passengers well.

    Boeing has sidestepped a lot of certification requirements in their history.  The 747-400 kept the same certification (with amendments) as the -200 even though the wing was different. This shortened the certification process.  The main technicality was not renumbering the slats.  Thats why you have a 1A and not fully renumbered.  Technicalities.

    The 737 has been redesigned so many time but always retains enough of the predecessor to be the same type for certification purposes.  While this make development fast and cheap, it does nothing to enhance safety, comfort and efficiency.  It is stagnating advancement and letting Airbus and others leap out ahead of the former king.

  5. The 727 and the 737 share the same cockpit section.  

    My point was initially that they are attempting to make 1060s technology integrate with 2000 technology and it has many issue.  From a pilot and backend perspective its all bright lights and shiny new things but under the skin is is a nightmare of independent systems trying to work together.  Does it work?  Sure.  is it efficient or reliable? not really.  Does it measure up to the competition?  not by a longshot.

     

  6. the current 737 variations are an abomination of 1960s, 1970.s, 1980's etc technology.

    The integration of systems is no-existent and is mainly duct taped together to create the aircraft.

    it may look pretty in the (lower) cockpit but behind those screens is still analog and steam.

    The type is WAY past its prime and needs a full replacement.

    Out of curiosity I wonder if the CL 515 could be adapted as a rescue aircraft. If so it would be a great aircraft for the RCAF. It could be used to fight forest fires as well as being able to get into small lakes as a rescue aircraft.

    Does anyone know whether it could be used as is, or developed that way.

    Not likely since the water tanks are integral to the fuselage.

    If we go ahead with the F35, I hope they will come without these problems, Afterall they will be some years in the future and the US has had many years to fix the problems but ....... 🙃

    The U.S. F-35 program has been dogged by technical problems and operational shortcomings that continue to pose safety risks and raise questions of mission readiness. Despite multiple delays, the most advanced (and expensive) warfighter ever mass-produced has critical issues highlighted by the Pentagon that still need to be reconciled for the jet to meet its lofty promises.

    On Tuesday, Canada announced it is finalizing plans to buy 88 F-35s for the Royal Canadian Air Force, with the first jet expected to be delivered in 2025. Lockheed Martin has in recent years made steady progress in resolving the F-35’s shortcomings, though the F-35 Joint Program Office told Defence News in 2021 the aircraft still had “critical” issues that have an “impact on mission readiness.”

    While the issues are classified, here are five problems that have been brought to light:

    The severe sinus pains

    Spikes in air pressure inside the cockpit caused pilots to have “excruciating” ear and sinus pain, forcing two Air Force pilots to abort test missions, according to a U.S. Department of Defence report. The pilots were using earlier versions of the F-35 and experienced barotrauma, or ear injuries related to changes to air pressure, “causing loss of in-flight situational awareness, with effects lasting for months,” according to the document.

    A design change was expected to fix the problem in 2019, however, it is still one of the unresolved issues highlighted a year ago.

    Supersonic flight causes stealth coating to detach

    The F-35 can only tolerate supersonic speeds at high altitudes for short bursts before it sustains lasting structural damage and the loss of stealth capabilities. During high speeds, the jet’s stealth coating, which makes it invisible to radar, is known to bubble.

    There are currently no plans to correct the problem. The F-35 JPO told Defense News the issue was closed under the category of ‘no plans to correct’ due to cost overruns and the time it would take to correct. Instead, the Pentagon set a time limit for supersonic flight to less than a cumulative minute for all models.

    Despite this significant limitation to its stealth and dogfighting capability, the F-35 has advantages over its predecessors in ground attacks and intelligence gathering. But repair times and flight costs remains an issue in making the F-35 the versatile weapon it was conceived to be.

    Repair times and cost to fly

    Every hour of flight costs US$36,000 on average , with Lockheed claiming it can reduce the cost to US$25,000 if the JPO awards it an exclusive maintenance contract. By comparison, the F-22 runs US$22,000 per hour of flight.

    According to the U.S. GAO, the F-35A, which is used by the Air Force, would cost US$7.8 million per plane for one year of operation, $3.7 million more than the Air Force’s target for affordability. Unless the costs can be brought down, the repair costs for Canada could climb well into the billions by next half of the century.

    ‘Green glow’ obscures pilot’s vision at night

    The F-35’s helmet-mounted display would emit a bright glow in low-light situations that obscures the pilot’s vision. One Air Force pilot on an air-to-air refuelling mission last year lost sight of the tanker as he drew closer to it, causing a near crash. Investigators said the display glowed too brightly, even on its lowest level, according to Air Force Times. While it’s not known how common the problem is, both a software upgrade and a newer headgear using an OLED display as opposed to LCD were proposed to address the issue and are expected to be implemented before 2025.

    The Unknowns

    The F-35’s mission capability rating sat at 69 per cent early in 2021, falling short of the 80 per cent benchmark set by the the U.S. military, with progress appearing to plateau. For part of the fleet, the canopy and engine power modules were highlighted by the previous U.S. administration as ongoing issues.

    Seven critical technical deficiencies were reported in July, down from 11 in January. While the nature of the issues classified, all remaining deficiencies belong to 1B issues, which stands for problems with “critical impact on mission readiness.”

    There is something to be said for the opposite strategy of build em cheap and build a lot of them.  This Aircraft is trying to do too much and does none of it better than the competition.  It is also missing one engine

    “ Warfarin is a type of medicine known as an anticoagulant, or blood thinner.

    It makes your blood flow through your veins more easily. This means your blood will be less likely to make a dangerous blood clot.

    Warfarin is used to treat people who have had a previous blood clot, such as:

    It's also used to prevent blood clots if you're at high risk of having them in the future.

    correct, however it is also used as rat poison.  It causes Rats the hemorrhage and bleed out.  Dosage of blood thinners is tightly controlled to prevent harm. 

  10. if everyone in Ontario (for instance) were to go out this month and buy an electric vehicle, the Power grid would be brought to its knees just like in 2003.  Our current power infrastructure cannot even handle a hot day in July without brown outs.  Now add 14 million electric cars all soaking up their share of electrons.  Ain't gonna happen.  It would kill the grid.

    Until the government spends the necessary money to improve the power grid and ensure a substantial reserve, electric cars will remain niche in the near term.

    Our reliance on oil will continue for decades.  Even electric cars need oil anyway, lots of plastic there.

    As for shipping oil to Europe.  There is no worry there because we can't even ship oil to our own east coast. 

    The priorities of this government are misguided for sure.

    For whatever reason our governments and big pharma have pushed the idea that the only way to defeat the pandemic is through vaccines.  There has been virtually no attempt to deal with the idea that Covid sufferers could be treated and when independent groups with very little voice claimed, rightly or wrongly, that they had treatments they were ignored by both government and the mainline media. Personally I see it as criminal and maybe that will come to be the case.

    It is obvious that there is a lot more money to be made with a vaccine that there is with a treatment. Ultimately it has been shown that the way out of this is herd immunity that they may or may not have been helped by the vaccines, but in the meantime there have been those that have suffered or died as a result of not having had any focus being put on a treatment with the research on treatments that did take place being either ignored or summarily discredited.

    Here is a current account of a treatment that comes out of Australia that is showing promise. 

     

    COVID-19 Beware: Cheap and Widely Accessible Drug Could Fight Virus

    COVID-19 Beware: Cheap and Widely Accessible Drug Could Fight Virus

    By Lily Kelly

     April 7, 2022 Updated: April 8, 2022

    Researchers from the Australian National University (ANU) have discovered that the cheap and widely used drug, heparin, when inhaled can be a uniquely effective prevention and treatment method for COVID-19.

    Heparin is currently used to prevent blood from clotting and it is typically administered through an injection.

    However, early results of an ANU clinical study show that inhaling heparin helps prevent those with COVID-19 from developing lung damage and shows promise in protecting people from getting the virus.

    The results were collected from trials conducted in American hospitals where researchers monitored the effect inhaled heparin had on patients hospitalized with COVID-19, to determine the drug’s ability to combat the virus and its safety.

    The study found that after inhaling a course of heparin the breathing and oxygen levels of 70 percent of the subjects improved, along with their symptoms according to the World Health Organization COVID symptoms scale.

    There were 98 patients studied in the early trials, with the average age of the subjects being 66. There were also slightly more men than women in the study.

    The ANU is still conducting multiple other clinical trials in 11 more countries but researchers have said the initial results are promising.

    Lead researcher of the study, Prof. Frank van Haren, said in an ANU news release that heparin if proven effective and safe, could majorly impact the world’s fight against COVID-19.

    “This drug is already available in hospitals all over the world and it is a very inexpensive drug,” van Haren said.

    “This could really assist in poorer countries where vaccination is challenging and we think it could help front line workers who could use it as a preventative measure.”

    Prof. van Haren said that an effective treatment of COVID-19 is still needed and that the majority of experts on COVID-19 agree that the pandemic will not be stopped by vaccinations alone.

    “Inhaled heparin is a promising new possibility to provide a low-cost, safe and effective treatment for COVID-19 that is available and affordable to low and middle-income countries around the globe.”

    He said that once heparin is proved to be safe and effective, inhaled heparin could be used everywhere as a treatment for the virus, within months.

    Co-lead of the global studies of heparin, King’s College University Professor Clive Page, said in the news release that heparin is individually effective against COVID because unlike other drugs it’s anti-viral, anti-coagulant, and anti-inflammatory.

    Page said that inhaled heparin effectively stops the virus from infecting lung cells by binding to the virus’s spike proteins, which the coronavirus uses to enter cells. This prevents people from contracting the virus.

    Heparin strongly binds to the coronavirus’s spike proteins because its structure is very similar to Heparan Sulphate, a molecule at the surface of the human cell that the virus binds its spike proteins to when entering a cell.

    Heparin acts as a decoy for Heparan sulphate, binding to the virus before it can bind to the cell molecule.

    “It’s also a blood thinner, Page said.” “When COVID-19 patients get very sick they develop blood clots in the lungs and these can be lethal. Heparin stops these clots from forming.”

    He said that when the body launches an exaggerated response to kill the virus, heparin can calm everything down.

    “We already know heparin can reduce lung damage caused by this inflammation and the immune response overdrive that we see in other lung diseases which could provide benefit to patients hospitalised with COVID-19.”

    The project’s researchers said that the anti-viral and anti-inflammatory nature of heparin is what makes the drug useful as both a method of prevention and treatment of the virus.

    There have been some concerns raised about the lack of younger people involved in the study, particularly menstruating women, who can develop heavy periods from blood thinners.

    However, in an email to The Epoch Times, Prof. van Haren, said that patients of all age groups from 18 years and older have been included in the ongoing trials that are being conducted around the world.

    “So far we have seen a similar effect in all patients regardless of age,” van Haren said.

    He said that the doses of heparin that they gave their patients to inhale had no relevant effect on the body’s ability to clot blood.

    “Because the inhaled heparin does not have a blood-thinning effect in the body (only locally in the lungs), there is no effect on menstruation and no risk of other bleeding for patients,” van Haren said.

    Additionally, he said that the treatment was safe for people with anemia.

    The news of heparins efficacy comes after researchers at Melbourne university developed a heparin nasal spray to prevent people from contracting the virus.

    The Director of Melbourne University’s Lung Health Research Centre, Professor Gary Anderson said in a Melbourne university news release that heparin should work against all variants of the virus.

    “Importantly, this nasal spray should prove effective for all COVID-19 variants because the Heparan Sulphate binding site is essential for infection, and is likely to be preserved in new variants.”

    According to ABC News, the spray is currently undergoing a six month clinical trial that includes 340 households in Victoria.

    heparin is a BLOOD THINNER.  Similar to WARFARIN which is RAT POISON.

  12. Micro-Sienna Deck boards and lumber (Brown Pressure Treat) need at least 1 season to properly dry and acclimatize before staining or painting.  Do it too early and you are in for increased maintenance.

    If we were still allowed to use the good stain from years ago it wouldnt be an issue but it is banned in Canada.

    And we’ll just have to wait for the platitudes to flow from Trudeau on how well he has managed the country through the hard times, having our backs and all.

    Billions for universal dental, pharmacare, housing for Troc to keep the NDP happy and now this :

    I think we’ll see the military shuffled down the priority list for another few years.

    How did you miss this in the latest news cycle.  It was indeed covered.  at least on CTV News.

  14. There will be a real food shortage in Europe and north africa because fully 1/3 of all wheat production comes from Ukraine for that region.  They are entering the spring planting season now and are unable to plant due to the pesky war (special operation) whatever.  Sanctions or not, it will not be a good couple of years.

     

  15. so the article clearly says they were all processed by BBP and were repatriated to Haiti.

    It is not clear if ALL of them were repatriated.

    Thats how it works.  you show up and claim refugee status then a determination is made.  Nothing truly illegal about it other than they did not land at a port of entry.

     

  16. Look.  The Healthcare system is there to help ALL PEOPLE.  However the healthcare system also demands that people do their part to ensure they remain healthy.  There are thousands of resources to achieve this and yet most don't take advantage of them.  One of those resources to help you remain healthy is Vaccines. 

    If everyone did their part we would be back to normal by now.
