See Newtown's First Law of Motion.
Assuming you mean "Newton's", congratulations, you just referenced something irrelevant. Matter outstanding.
Humans can see airplanes over extended periods of time and be able to note when their courses do not match tracking data or follow sensible flight paths.
I asked you to substantiate your claim, not restate it with more words. Please pay attention. Matter outstanding.
Wrong. In the case of MN379: The tracking systems would have worked, but someone or something turned off the transponder and its backup. In the general case, FlightAware and its ilk are accurate within 5 minutes see: http://flightaware.com/about/faq#howlive
Thank you for the link. I'm pleased to see that it confirms my suspicions about how the data is calculated (granted, it's not surprising that it does, since I sourced my original claim from the very same page):
FlightAware compiles, aggregates, and processes data from over 45 government sources (in Europe, North America, and Oceania), dozens of airlines, commercial data providers, as well as hundreds of receivers in FlightAware's ADS-B flight tracking network. FlightAware's proprietary algorithms calculate delay and arrival time estimates to offer the most up-to-date and reliable flight tracking data on the Internet.
Oh my. You didn't think it magically tracks every plane's every move, did you now?
Please tell me where I made any assumption or based anything on a false assumption.
See multiple matters outstanding above.
Also my post was a challenge VH's unsupported claims. VH amde the claims, so you should be challenging him, not me.
As you rightly pointed out, Vauxhall is already being challenged - there's no point in two people doing the same thing. Meanwhile, someone needs to keep you in check - otherwise people might think that you actually put some effort into your posts, or even be tricked into believing you.
