  1. Wow, you must be really desperate for an October surprise, with 4 days left. No sources, no independent confirmation, and Hunter's not running for president. Again, needs proving and many of us are on record saying otherwise. Even Fox won't publish this crap.
  2. Nobody was saying the OSTP report claimed that ending the pandemic among the accomplishments of the administration. Everybody was talking about the press release that did. Why are you setting up strawmen?
  3. It's really weird that he describes the left as "raving leftist psychoses" who are "overemotional" when you remove the word "leftist" it pretty much describes him. It actually sounds like he's the most emotional person here.
  4. I'm surprised you haven't heard of it - when it made its first flight, lots of skydivers here noticed. Added link: https://www.flightglobal.com/airframers/all-electric-grand-caravan-makes-maiden-flight/138600.article And the CEO of MagniX who make the motor, is a skydiver. He was interviewed by Pete Allum which I posted here earlier - https://youtu.be/oE1P84Qt2tg
  5. You must have missed the electric C208 already flying: In the UK and Europe the C208 is one of the most common jump planes around. MagniX are going to market it for cargo ops, which is pretty much the exact configuration for skydiving. The 3 DZs near me operate: C208, C208 (3 aircraft), PAC 750XL.
  6. The original was likely removed or changed, as WH communications director has admitted it was "poorly worded": https://www.forbes.com/sites/jackbrewster/2020/10/28/white-house-claim-that-trump-ended-the-pandemic-was-poorly-worded-spokesperson-says/ - they're not denying it If I had was in a football team in the premier league and we were down 16 points halfway through the season, I wouldn't say we were "winning" the league, especially when the past several matches featured own goals. The thing about "ending" vs. "ended" - I've been seeing this from Trump supporters since yesterday, did you get your script late from your handler? I mean, couldn't you choose a more original hill to die on?
  7. They'd be a really good place for a clean-sheet design though. The load alleviation they'll add would come in useful. And if they can take any shear like Elon claims his new cells could, that would be even better.
  8. I'm also aware of this, I was directly involved in several civil aircraft certification programs. Problem is the wings might have been designed for fuel rather than batteries, so it will depend on structural margins. Much of the certification effort goes into the wing loads - luckily limit load scenarios are usually calculated as wings empty - maximum upbend, whereas batteries are always there and will provide load relief in that case. However scenarios such as steep dive and landing at MLW will become the critical cases to certify for. So those will have to be checked, I'm not sure where the batteries are in the Harbour Air DHC-2s but I think conversions could be easier for those aircraft with batteries in bottom cargo like C208s or use the space in front where most of the old engine used to be.
  9. Given how Teslas have held up (one model S has been driven 1 million km) and how easy it is to change battery packs? Changing the battery pack will instantly refresh performance to new and will not be anywhere as invasive as changing a turbine or piston engine for example. No, people will upgrade because there's a newer, better aircraft model available with better performance, probably the clean-sheet electrics. Apple secretly degraded their iPhone performance when the batteries degraded but got caught when some people did battery replacements and found that performance suddenly increased.
  10. They made a few claims in that video: the market has "predicted" incumbent wins or losses right several times before the interviewee then explained why the numbers go up or down based on what the market thinks critically, they did not explain WHERE the markets get their prediction/opinion from. They probably look at the polls, and either agree/disagree with it but there seems to be no other source of information besides the polls, and instinct So sure, they guessed right several times, but they didn't show how the polls were doing when they guessed right. They didn't make those guesses in a vacuum. The markets are made of humans and they don't have any special knowledge that's not available to the general public. Heck, several posters here are investors. Their collective "guess" on who wins is shaped by their personal circumstances and the information they personally get, their demographics might make it different from the polls, but if you take their word as gospel then you're really just using them to process the news and polls for you.
  11. Agreed, I feel much safer in a turbine than a piston but there are still plenty of piston DZs around. However, gearbox reliability IS a limiting issue - turbine power output is actually constrained by this, which is why Pratt&Whitney took more than 20 years to apply them to civil airliners via the GTF. Plenty of helicopters also have systems monitoring for metal chips in the oil system as gearbox failure there is the main killer (although admittedly, fixed-wing turbine safety record is much better than helicopters).
  12. Sure, but they're not really sources of information BEFORE the election. At least, in terms of generating information that can be used to predict the winner. Richravizza uses the stock market as a source of "information", but doesn't really ask where they get their information from. I doubt companies' quarterly financial results contain much information on who might win.
  13. And if you use the stock market to predict the winner, how do the stock market traders know who's going to win? Do they have polls of their own? Even if the big institutional investors had some kind of access to private information, the likely election winner is NOT private information, it's public information because it's the public who decides the winner.
  14. Except for the inability to stop/start them frequently without shortening service life. And their weak point is still the gearbox which electrics can dispense with. Airbus is actually proposing hybrids which have electric motors powered by a turbine - having a fixed torque generator would get the best out of the turbine while overcoming the range and energy density issues of batteries.
  15. As others have said the stock market has already priced in a Dem victory, as they can see the polls too. Now whether the polls are accurate is another thing, but your point that there are many "hidden" Trump supporters the polls are missing has no evidence for it. The link contains more details. Pollsters don't count "number of Trump bumper stickers" or "biden/harris" yard signs, you know?
  16. Nate Silver's FiveThirtyEight, who predicted the largest odds for Trump winning in 2016, says: So yes, keep hoping. Trump DOES have a chance to win, just that this number is way below 50%. Edit: source link: https://fivethirtyeight.com/features/trump-supporters-arent-shy-but-polls-could-still-be-missing-some-of-them/
  17. Well...possibly because I did it in the form of a silly prank I had to own up though, because the school threatened to punish everyone if the perpetrator/s didn't come forward (collective punishment is banned under the Geneva Convention, but Catholics have better morals, right?)
  18. Maybe richravizza is saying that Trump's tweets are a false narrative. Which is correct.
  19. It's not. You do it all the time. I also criticise Islam, and I've never been punished for it. I was, however, suspended for a day from the Catholic school I attended because I criticised Christianity.
  20. Oh yes indeed. "We hold all the cards" "They need us more than we need them" "The German automotive industry will force Merkel to do a deal" And that's just a tiny fraction of the lies Interestingly, the brexiters I know have now changed their tune to "it will be bad at first, because change is always disruptive, but it will be good in the long run". When asked "how long?" they don't have any idea, of course. But it will be great!
  21. I am also noting with some glee how Johnson is getting scared big brother Trump won't be able to come to his rescue: I got skin in this game, please vote him out!
  22. The 1918 pandemic killed lots of people, then mysteriously "disappeared". The RNA polymerase in influenza viruses is error-prone so mutation rates are fast - the 1918 virus mutated in 2 critical sites and became a lot less deadly, so it actually didn't disappear - it just became the regular flu (the H1N1 family that we still have today). Why? Viruses actually face selection pressure to become less deadly, as if they kill their hosts too quickly they won't be able to reproduce as effectively. This is what happened to the Spanish flu. However, for Covid-19, the RNA polymerase in the coronavirus has better "proof-reading" mechanisms, so mutation rate is much slower. Sequencing the genome from the start of the covid-19 outbreak to now there's only been minimal change. So if we want to wait for this virus to become less deadly like the 1918 one, we're going to have to wait a LONG time. The upside is, since mutation rates are much slower, it should be easier to target with a vaccine and drugs. Unfortunately no vaccines or drug treatments have ever been developed for coronaviruses, so scientists are in new territory here. As destructive as Covid-19 is, it won't be the last pandemic. It's not a matter of if, but when. If we don't learn from this, the next one could be much worse. And when the next one comes, would you want Trump to be the one leading the country again?
  23. The CEO of MagniX is actually a skydiver himself, and he's been interviewed by Pete Allum: https://www.careallfoundation.org/blog-article-9-roei-ganzarski-ceo-magnix One thing that's also great for electrics is potentially far better safety - carb icing, gearbox failures and most other mechanical failures would become a thing of the past. I'd be far more relaxed between takeoff roll and 1500 feet!
  24. I used to think this was correct, unfortunately there have now been confirmed cases of surface transmission of covid-19: https://www.rnz.co.nz/news/national/427446/rubbish-bin-the-likely-source-of-covid-infection There has also been a study that covid-19 particles survive longer on surfaces than influenza viruses: https://www.bbc.co.uk/news/health-54500673 I also used to think this, but this is now outdated as we've had more studies come out: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7277485/
